RE: Site hanging randomly.
Is it the same time of day? If so, check scheduled tasks and see if something is running that conflicts or is consuming resources.

Re: Site hanging randomly.
Is the server responsive when CF hangs? Or is it a bit slow/unresponsive as well? I had some serious crash issues with CF9 64 bit a few years back and switched over to railo after trying to debug it for weeks without result. Make sure to check the windows logs if there are any weird events before CF hangs. My problem was mainly with JVM GC not doing its work properly and eventually kill CF. You could try to upgrade your JVM to a newer version that is officially supported, but not sure if that will help your issue (trialerror).

Re: Site hanging randomly.
I hadn't thought to check a static resource to see if it was still
available. I'll do that next time it hangs.
I'm currently running jdk1.6.0_32 with these JVM arguments:
-server -Dsun.io.useCanonCaches=false -XX:MaxPermSize=512m
-XX:+UseParallelGC -Xbatch -Dsun.rmi.dgc.client.gcInterval=60
-Dsun.rmi.dgc.server.gcInterval=30
-Dcoldfusion.rootDir={application.home}/../
-Dcoldfusion.libPath={application.home}/../lib
The server has 6 Gb of ram and 4 CPU cores.

Re: Site hanging randomly.
have you checked the coldfusion server monitor ?
I would also suggest installed FusionReactor for some addiitonal monitoring.
check the coldfusion-out logs for issues.

Re: Site hanging randomly.
coldfusion-out says a couple things like:
* A non-SQL error occurred while requesting a connection from DB Name.
* Timed out trying to establish connection
* 3/13 16:19:21 Information [jrpp-2087] - HTTP request completed {Status
Code=503 ,Time taken=84723 ms}
Before it stops responding.
Will watch server monitor again. I have in the past but didn't find the root
cause.

Re: Site hanging randomly.
That does sounds like a possible cause.
Do you have long running code with multiple queries or some sort of heavy
reporting query of some sort?
Network interruptions? Latency?
Do you always have the CF monitor running? If so, try to turn off all the
monitoring as that was buggy in CF9 if I remember correctly (JVM killer).
Just naming a few options to think of. Good luck.
