We are running CFMX 6.1 on RH 7.3 with Apache 1.3.27-4. The machine is
a Dual 1.5GHz Athlon server with 1.5GB of RAM and a 100GB 4-disk Level
5 RAID. We use MySQL 3.23.58, running locally (DNS and mail also run
locally - this is our "primary" server for everything, we have 2 Win2k
servers that aren't really used for anything except file storage.)
Client vars are stored in the system registry, I've never set up a
datasource for them, although I don't use the client scope in any
applications (I use session scope, since there's no cluster.)
We have about 61 active virtual hosts on the server, though only a
handful really use CF or SQL. CF is a clean install of 6.1, and I've
changed the JVM parameters to use 256MB of RAM. I'm still losing
contact with CF about once an hour (I've got a cron job running to
restart CF at 55 past the hour.) It doesn't happen EVERY hour, of
course, but in the cfserver log, I have a number of these errors which
seem to be at the heart of the problem:
java.lang.OutOfMemoryError: unable to create new native thread
at java.lang.Thread.start(Native Method)
at jrunx.scheduler.ThreadPool.spawnHandler(ThreadPool.java:239)
at
jrunx.scheduler.ThreadPool$ThreadThrottle.createRunnable(ThreadPool.java
:404)
at
jrunx.scheduler.ThreadPool$UpstreamMetrics.createRunnable(ThreadPool.jav
a:269)
at jrunx.scheduler.WorkerThread.run(WorkerThread.java:62)
The stack traces I've done have no jnpp entries, so it doesn't seem to
be any pages causing the problem. (FYI, the scheduler is usually quiet,
our clients send out the occasional newsletter, but that's only 1 task,
and it doesn't correspond with all the crashes we've been getting.)
I think that's the bulk of the data I've been able to gather about
this. If you have any insights, I'd greatly appreciate them! :) Thanks
in advance,
Ken
