Troy, After upgrading to JBoss 3.2.2 in our RH Linux 7.3 IBM JDK 1.4.1 environment, JBoss kept running out of memory every couple hours. I don't know if this will help, since the hardware is different, but I created some monitoring plugins based on information in the very handy IBM JDK Diagnosis Documentation:
http://www-106.ibm.com/developerworks/java/jdk/diagnosis/diag141sr1.pdf Eventually, I determined that the snmp-adaptor.sar service added in JBoss 3.2.2 used too many deployment descriptors: http://www.mail-archive.com/[EMAIL PROTECTED]/msg33807.html I removed the SNMP service and the machine stopped crashing. Your problem is probably completely different, but the Diagnosis docs helped me tremendously. -- Chris Bonham President/CEO Third Eye Consulting, Inc.
