Subject RE: Tomcat manager app stops responding
Date Mon, 09 Aug 2004 13:52:26 GMT
My log files were being deleted by the deployment process so I was getting
nothing from them, I fixed that problem and will watch the logs today and
see if they show anything when it occurs.

BTW, any ideas on how to get a thread dump of the JVM on Linux?

I am definitely not out of memory but I will modify CATLINA_OPTS to dump the
GC statistics.

Please check back tomorrow after I have a day of logs.

A couple.  A situation as generic as, "never responds" gets generic
1/ Check a thread dump of the JVM (search the archives if you don't know
how), see whether something's deadlocked.  Slim chance, but worth a shot.

2/ Check memory usage and GC, perhaps use a profiler.  GC can make an app
appear several shades of unresponsive.

3/ check the logs

I don't know about this one, so I'll leave it for someone who does.
