Re: [ACFUG Discuss] ColdFusion Builder freezes abruptly
I wanted to echo Cameron's email.. I experienced similar. I wanted to also share another alternative that I have switched to: intellij IDEA. Multi-language support, but understands CF. Has a fast extended find and the ability to export search results. Also understands source control out of the box. It is commercial with a price tag, but well worth it.

If you can't get CFBuilder working to your satisfaction, you might also take a look at Sublime Text 2, which I started using exclusively about a year ago. It uses way less memory, is very snappy, and has CFML extensions available. http://www.sublimetext.com/ I'd gotten to the point that I had to give CFBuilder/Eclipse about a third of my whole machine's memory for it to run and it still paused all the time for garbage collection. Sublime Text is crazy awesome compared to CFBuilder in that regard. -Cameron -- Cameron Childress -- p: 678.637.5072 im: cameroncf facebook | twitter | google+
Re: [ACFUG Discuss] CF 10 and REST and wtf?
so far no luck. Host just reset things but problem came back after
another day. I get one of these IIS 500 pages
https://app.box.com/s/5iarseihfwzxdnqn6ecs
The CFC I have setup is real basic for testing this issue, it should 'just
work!'
something like this
component restpath=/works rest=true {
remote any function getAll() httpMethod=GET
produces=application/json{
return {foo:42};
}

Any luck on this? You said it never fails on local server so I guess
someone (haha me) testing it locally for you wont help.

Its a really simple thing too. When this REST call fails, a test page
using the model.Content.ContentService runs fine. So it has something to
do with the REST gimmickery.

[ACFUG Discuss] Out of Memory?!?
All, I'm trying to figure out and determine a Jrun Out of Memory error. I get the following in my logs: [Thu Aug 08 14:40:14 2013] [notice] jrApache[2937: 31182] returning error page for JRun too busy or out of memory [Thu Aug 08 15:50:09 2013] [notice] jrApache[1787: 63699] returning error page for JRun too busy or out of memory It doesn't happen often, (maybe once or occasionally twice a business day) but as everyone understands, users aren't happy when it happens to them. This is a linux box, 64bit Centos 6, CF9 Enterprise, 64bit jvm version 1.7. (The jvm was installed separately from CF for security and coldfusion uses it.) I doubt it is actually an out of memory condition (though I could be wrong) The server has 6GB of physical memory and another 6GB of swap. It rarely needs to use swap. (i.e. I have not observed it.) The jvm is given significant memory to use as well. It is using a 64bit jvm with the settings of 1GB min JVM heap, as well as a 3GB max. When I look through the server monitor, it is normal to see 1 to 1.5GB allocated and between 100-750MB used. (I see a normal sawtooth pattern with the memory usage, so it looks like what I would expect from the garbage collection routing. It does spike occasionally but I have never seen it close to the 3GB max. (I've never even seen it hit 2GB used.) The server is set for 40 template requests (I recently upped it from 10 to see if that was the problem and it still occurred with the same frequency.) Flash remoting is set to 2, webservice 1, CFC 1. (These remote settings are only set for the monitor, as the server does not provide any webservices outside the running application) Jrun is set to 50 requests, and 1000 queued. (Enough to cover the CF requests.) I looked at Charlie's blog... I have checked the logs, and other than the apache error log (above) I do not see anything. I've check the system /var/log/messages, I've checked all the CF logs (I also archived everything yesterday, and the cf logs are practically empty even after today's occurrence.)

RE: [ACFUG Discuss] Out of Memory?!?
I'm looking at your error and seeing that it is merely reporting back that the server is busy but does not give a definitive cause. While it could be memory, I think I'd be looking for CPU usage issues. What does the CPU usage look like during this event? I ran into a similar problem a couple of years back when the company I worked for at the time went to virtual machines (albeit we were using 32 bit Windows and not Linux). A process was running that had nothing to do with Jrun or IIS/WWW that was sucking up the CPU all the way to 100% and there was no CPU left to process requests. I was getting the same 503 error that you get when you try to request a page from the server. Restarts only postponed the problem and our fix was simply to spin up a new virtual machine (a 64bit instance). We never could completely isolate the exact process that was eating up the CPU. Just a thought, hope you're able to find the problem quickly!

RE: [ACFUG Discuss] Out of Memory?!?
Like you, I would think this is not memory related. I think that's just a really old error message, from the days when even the then Macromedia engineers could only throw up their hands and guess when something was amiss. I recently saw this error message happening for a client where we found (since they were on IIS) that the jrun_iis6_wildcard.logs (in [ColdFusion9]\runtime\lib\wsconfig\nn\LogFiles) had indications of errors also. I realize you're on Apache, and you say you looked at all the logs, but did you check out those logs in that wsconfig dir and its subdirs? It's just a stab in the dark whether any log messages there (around the same time) will be useful. I would focus on something making the CF instance not responsive. I know you said you raised the simult request threads from 10 to 40, and it seemed fine at 10. But maybe you have new load, or a new problem that makes requests hang. As Ajas said, FR (or as you're using it, the CF Server Monitor) can show you any running requests (the CFSM only show them if you turn on start monitoring). If you can be on when it happens you may be surprised what you find. If all 10 (or now 40) are hung, even if only for a while, that could lead to the error-not that CF's down, but the connector thinks it can't be reached. And as you noted in a later message, turning on the alerts will help (in either CFSM, again where start monitoring must be enabled for them to work, or in FR, or SeeFusion), as that will give you info even when you can't be watching the monitors. Since you're using the CFSM, and you say you configured the alerts, did you confirm that you get the email they send? There's no test feature. What I do is set the memory alert to below the current memory used, which should trigger an alert within a few minutes. But then I turn that alert off. I find it useless, since the JVM (since 1.5) can often let used memory climb to the max before deciding to do a major GC, so you can get those memory alerts when there's no real problem, if indeed a GC at that point would have collected a lot of not really used memory. But I do recommend that slow server alert in the CFSM, or the running requests alert in FR. For almost everyone, if you have many requests running at once, that's a canary in the coal mine indicating that problems may be afoot. The question then is whether the alert shows many slow requests. If it just shows many fast ones, then that is just a sign of a lot of traffic, and if it's being handled fast, you need to increase the number of max simult requests, and the alert level in whatever monitor you're using. And be careful about setting the other values in request tuning so low (web services, flash remoting, and remote cfcs). There's never a harm in them being more than you need. But if they are less than you need, that could be where a bottleneck happens. I know you say you don't serve web services, but I've seen shows have their own cf pages calling their own CFCs as web services. And if that request limit was low, then that becomes a single threading bottleneck. Or maybe you DO have code calling CFCs remotely (via ajax). Or about flash remoting, the monitor (and FR) use those, and your own code may (even if unexpectedly). Again, why constrict them? If you don't use them, there's no harm in them being larger (like 5 or 10, each). Finally, note that you could have cf requests using either cfthread or reporting, and there are limits for each of those (configurable in the admin). And though you are not using CF Standard, I'll say for other readers that they could have all this sort of problem caused by using some tag that is itself single-threaded in CF Standard, as are many tags, including cfdocument, cfpdf, and more. That could cause a low traffic site to still have hung requests. Let us know if any of that helps, or not. But yes, if it remains and you don't solve it, I am available for consulting, and with my satisfaction guarantee, you don't have to pay for time you don't feel is valuable. /charlie From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Frank Moorman Sent: Thursday, August 08, 2013 7:42 PM To: discussion@acfug.org Subject: [ACFUG Discuss] Out of Memory?!? All, I'm trying to figure out and determine a Jrun Out of Memory error. I get the following in my logs: [Thu Aug 08 14:40:14 2013] [notice] jrApache[2937: 31182] returning error page for JRun too busy or out of memory [Thu Aug 08 15:50:09 2013] [notice] jrApache[1787: 63699] returning error page for JRun too busy or out of memory It doesn't happen often, (maybe once or occasionally twice a business day) but as everyone understands, users aren't happy when it happens to them. This is a linux box, 64bit Centos 6, CF9 Enterprise, 64bit jvm version 1.7. (The jvm was installed separately from CF for security and coldfusion uses it.) I doubt it is actually an out of memory condition (though I could be wrong) The server has 6GB of physical memory
RE: [ACFUG Discuss] CF 10 and REST and wtf?
Doug,
Not sure if this is related to your issue, but I read at the following link
about having to refresh the rest services.
http://www.anujgakhar.com/2012/02/20/using-rest-services-in-coldfusion-10/
Look at the discussion below the blog post. I am about to begin a REST
project so I am interested in your results. Although, in my project, I have
access to the CFAdmin.

Bill Beers

so far no luck. Host just reset things but problem came back after
another day. I get one of these IIS 500 pages
https://app.box.com/s/5iarseihfwzxdnqn6ecs
The CFC I have setup is real basic for testing this issue, it should 'just
work!'
something like this
component restpath=/works rest=true {
remote any function getAll() httpMethod=GET
produces=application/json{
return {foo:42};
}
}

Douglas,
Any luck on this? You said it never fails on local server so I guess someone
(haha me) testing it locally for you wont help.
Let us know what you find. :-)

We cannot become what we need to be, remaining what we are.
No matter what, find a way. Because thats what winners do.
You can't improve what you don't measure.
Quality is never an accident; it is always the result of high intention,
sincere effort, intelligent direction and skillful execution; it represents
the wise choice of many alternatives.

tooling around a wee bit on something old and re-working a site with Angular
+ Bootstrap...its fun. So I figured I'd make use of the fancy new REST
stuff in CF10. Simple to set up, no need to use the CFAdmin to setup, and
bamm! Deploy to shared host, bamm! well, maybe not. Seems to consistently
fail after initial success. I push up the CFC, test, all is good. Come
back 1,2, or 12 hours later, its random, and the REST call is failing with
HTTP Error 500.0 - object is not an instance of declaring class
Anyone have any clues? No access to CFAdmin of course. It never fails on
the local server.
Its a really simple thing too. When this REST call fails, a test page using
the model.Content.ContentService runs fine. So it has something to do with
the REST gimmickery.
component restpath=/content rest=true {
remote any function getAll() httpMethod=GET
produces=application/json{
var service = ;
var entries = ;
var works = ;
service = CreateObject(component,
model.Content.ContentService).init();
entries = service.getAllItems();
response = serializeJSON( entries );
return response;
}
}
