Re: [ACFUG Discuss] Out of Memory?!?
All, Again, thanks for the help. I found the real jrun logs (which is something I speculated about initially.) With CentOS/CF9 the jrun logs are not under */opt/jrun4/ *but they are actually located at */opt/coldfusion9/runtime/logs/*. Needless to say, the jrun logs were helpful. It appears as if nearly all of the 503 responses are due to incomplete file uploads. I am a little surprised that these errors are now being kicked out by jrun when in the past they made it to coldfusion. But because it seems that Java is not handling the error condition, I believe the reason why they no longer make it to coldfusion might correspond to when I changed from the JVM installed with coldfusion to a newer JVM installed separately. (I changed JVM's to get the latest security patches.) Because the number of problems is less than 1% of the files that are uploaded, and it appears that our resources are not maxed out when it happens, I am assuming most of the blame for the problems is due to a network error on the sender side. (Many of our end-users are spread out across the country and use home internet connections of varying reliability.) I made the suggestion to the site owner that I rewrite our old upload dialog (a plain form allowing up to 6 files to be uploaded at once) with an ajax based solution that will single thread the files one at a time. I am hopeful that by limiting to a single file at a time, there will be fewer network errors. Of course there is still the few 503 errors that happen without uploading data... There are not many and at the moment none are in the Jrun logs. I am hopeful that some of the changes I made in the last few days (including incoporating some of Charlie's suggest request changes.) might have helped. But my pragmatism trumps optimism when it comes to computers, so I convinced the owner to get a Fusion Reactor subscription. If/when the situation happens again, I'll have a few more tools to use to help figure out what happened. FYI, here is the log entry that led me to the upload determination... 08/13 12:41:48 error unexpected end of part java.io.IOException: unexpected end of part at com.oreilly.servlet.multipart.PartInputStream.fill(PartInputStream.java:96) at com.oreilly.servlet.multipart.PartInputStream.read(PartInputStream.java:179) at com.oreilly.servlet.multipart.PartInputStream.read(PartInputStream.java:152) at com.oreilly.servlet.multipart.FilePart.write(FilePart.java:257) at com.oreilly.servlet.multipart.FilePart.writeTo(FilePart.java:215) at coldfusion.filter.FormScope.fillForm(FormScope.java:253) at coldfusion.filter.FusionContext.SymTab_initForRequest(FusionContext.java:408) at coldfusion.filter.GlobalsFilter.invoke(GlobalsFilter.java:33) at coldfusion.filter.DatasourceFilter.invoke(DatasourceFilter.java:22) at coldfusion.filter.CachingFilter.invoke(CachingFilter.java:62) at coldfusion.filter.RequestThrottleFilter.invoke(RequestThrottleFilter.java:126) at coldfusion.CfmServlet.service(CfmServlet.java:201) at coldfusion.bootstrap.BootstrapServlet.service(BootstrapServlet.java:89) at jrun.servlet.FilterChain.doFilter(FilterChain.java:86) at coldfusion.monitor.event.MonitoringServletFilter.doFilter(MonitoringServletFilter.java:42) at coldfusion.bootstrap.BootstrapFilter.doFilter(BootstrapFilter.java:46) at jrun.servlet.FilterChain.doFilter(FilterChain.java:94) at jrun.servlet.FilterChain.service(FilterChain.java:101) at jrun.servlet.ServletInvoker.invoke(ServletInvoker.java:106) at jrun.servlet.JRunInvokerChain.invokeNext(JRunInvokerChain.java:42) at jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:286) at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:543) at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:203) at jrunx.scheduler.ThreadPool$DownstreamMetrics.invokeRunnable(ThreadPool.java:320) at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:428) at jrunx.scheduler.ThreadPool$UpstreamMetrics.invokeRunnable(ThreadPool.java:266) at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66) 08/13 12:41:48 error (JRun Service: ProxyService [jrun.servlet.jrpp.JRunProxyService@6988843a]) JRunPRoxyServer.invokeRunnable: java.lang.IllegalStateException at jrun.servlet.JRunResponse.getWriter(JRunResponse.java:205) at jrun.servlet.JRunResponse.sendError(JRunResponse.java:597) at jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:328) at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:543) at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:203) at
Re: [ACFUG Discuss] ColdFusion Builder freezes abruptly
My ColdFusion Builder 2 has decided to be finicky again. From the heap monitor the memory used is 250M of 358M. In the progress view( windowshow viewothergeneralprogress), I see a message like Building Workspace(Sleeping), then another line which is Refresh Content(Sleeping) What could it mean? Below is the error message, I get, when I try to close it using Task Manager Description: A problem caused this program to stop interacting with Windows. Problem signature: Problem Event Name: AppHangB1 Application Name: CFBuilder.exe Application Version: 0.0.0.0 Application Timestamp: 4d87abff Hang Signature: f9d8 Hang Type: 0 OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 1033 Additional Hang Signature 1: f9d82b147b6ad3097a0d9c822ca02a2a Additional Hang Signature 2: de0a Additional Hang Signature 3: de0a40479120ea8170f842d4122846d6 Additional Hang Signature 4: f9d8 Additional Hang Signature 5: f9d82b147b6ad3097a0d9c822ca02a2a Additional Hang Signature 6: de0a Additional Hang Signature 7: de0a40479120ea8170f842d4122846d6 Am I missing any hotfixes for CFB2 or something else? I am running Coldfusion 9.

And isn’t it funny how troubling software can sometimes be like a petulant child: just when you starting watch it, it tends not to act up. :-) But patience, grasshopper. Yep, let’s see how it goes over time. Also, turn on the progress view (windowpreferencesgeneralprogress), to view background communications between CFB and CF (if you have connected any projects to a server). That too can be insightful, and perhaps your issues are only under certain forms of communications between the two. As for other plugins, I would not immediately suspect that myself, no. I mean, aren’t those the ones that are built-into CFB? Everyone would be using them, and I promise not everybody has problems with CFB being resource hungry. As always, there is some explanation. You just need to find it. Hope the above (and below) will help. /charlie From:ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Chris Sent: Friday, August 09, 2013 12:51 PM To: discussion@acfug.org Subject: Re: [ACFUG Discuss] ColdFusion Builder freezes abruptly Charlie, Thanks for your advice. I turned on the heap monitor and it has not crashed since then. Heap size is 139M of total: 248M max: 495M mark:none . On doing garbage collection it drops to 64M of 248M If CF builder freezes again due to excess memory usage, I will increase the heap size. But, under Window-preferences-general-Startup and shutdown I see all plugins in that window are activated at start-up Coldfusion SQL Plugin Appcode generation plug-in ... ... Aptana scripting Automatic updates scheduler Could the fact that so many plug-ins are activated be causing CF builder to freeze? Also, I use Flash Builder 4.5(but that does not freeze often) lot of times along with CF builder. I understand some people have commented that Eclipse based IDEs are resource hungry even though my system was 8GB RAM I appreciate your prompt response and time. - To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by FusionLink - - To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -
