I'm currently experiencing stability issues with CF 8 standard due to what I
think is high traffic loads on the sites its running.
There are 6 sites on this particular instance of CF8 and collectively they're
averaging at around 750 pages per second which result in around 6000 SQL
queries per
that is a lot for standard edition. Enterprise is meant to be able to
handle more connections, but I have never tested the difference.
how many simultaneous requests have you got it set to handle.
average should be 10 per cpu/core
but you will need to tweak to see what it can handle.

I assume this is 32bit given the amount of RAM. If by 750 pages per second
(bursts up to 1250-1500) you mean ColdFusion templates executing (and I
assume you do) then you are getting quite a bit out of the server I'd say
and making good use of your xeon 3.3's :) Your options for tweaking
After months of stability, I'm once again getting the below error.
Restarting CF service and rebooting server have not solved it. Neither has
removing and re-adding the connector. Help?
Service Temporary Unavailable!
The server is temporarily unable to service your request due to maintenance
This is going to be related to isapi_rewrite - not CF (at least that's how I
read it). I would re-add or upgrade your isapi rewrite module maybe? Note:
I have not seen this error before - I'm just noodling.

I restarted World Wide Web Publishing Service (i.e. IIS) and it was
fixed. Scary and bad.

You can also look at your CF allocation in your jvm.config. The default
is 512kb, which is pretty small. With everything you have running on
this machine, your options here may be limited, and in a 32bit
environment you might only be able to bump this up to 1400 on the top end.

are you sure this server can cope with 50 simultaneous requests?
see my previous reply for calculations based on cpu.
If not then putting it up that high would cause more problems than queuing
the requests.
You really should try fusionreactor as I suggested, there is a free trial
version if that
I am with Russ on this. Get Fusion Reactor, and start getting *REAL*
information about how your server is running then you can make choices about
what to change.
The number of queued requests my lead you to increase the memory and the
problem to go away (for example) but without knowing, you

I'm pretty sure that's the native Jakarta ISAPI module in CF 10, not
ISAPI Rewrite.

I suspect that for future issues, you can just restart the application
pool, as described here:

Paul,
These settings are in line with what I would expect and implement myself. I
don't have much to criticize here - but I will noodle with you :)
You have Simultaneous requests set to 50. Check your proc usage you might be
able to go a touch higher if you have 8 cores - say 64 or 72 ... but
If you get this issue often then take a look at your app pool settings anf
sldo thr connector settings, both of which have various limits and timeouts.

Being a job site, aside from the search, are the other CF pages really
dynamic? You could maybe do things like dump all the job descriptions and
corporate jargon pages to html a couple times a day and serve those instead.
If you have that many page hits, ask yourself how many unique users you
