I have a couple machines with high load like you mention. I have just updated them all the latest jvm 1.4.2_6 And the new drivers mm suggests.
1 machine has run flawlessly for about 1 week, before it was tanking like every other day. The other had one blip after 4 days and now is looking good. I suspect from reading a lot of messages about this it is not an easy fix. I would try the updates and if you still have trouble its time to start the jrun logging and garbage collecting logging and get greasy under the hood. I have seen a lot of people tinkering with the jvm arguments, it appears that depending on your application they might be able to be optimized to fit your load. If you haven't don't those 2 updates I would do so asap, let me know how it goes gabe -----Original Message----- From: Katz, Dov B (IT) [mailto:[EMAIL PROTECTED] Sent: Monday, November 29, 2004 7:14 AM To: CF-Talk Subject: RE: Mx hanging no available threads With the metrics you've been doing, have you come to a conclusion as to how to avoid this? Are there better garbage collection flags to set up with CFMX than what's running by default? I've seen a death of my server, but it's ended up manifesting itself in arbitrary requests returning Jrun Connection Protocol Error, (some threads return that, others work just fine)... ultimately leading to a "Cannot connect to the Jrun Server" (when cfmx just dies out)... I have a pretty heavy load on the machine (600k hits a day or thereabouts).... Any ideas would be appreciated...

What are the specs of the machines you are seeing this on?

After running perfectly for about 4 days she hung up. I took a look in the default-err.log to find a bunch of these java.lang.RuntimeException: Request timed out waiting for an available thread to run. You may want to consider increasing the number of active threads in the thread pool. at jrunx.scheduler.ThreadPool$Throttle.enter(ThreadPool.java:125) at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java :448 ) at jrunx.scheduler.ThreadPool$UpstreamMetrics.invokeRunnable(ThreadPool.jav a:29 4) at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66) Has anyone encountered issues like this before? gabe ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:4:185505 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
