Environment: IBM JDK 1.4.1 SR1 JAVA_OPTS: -Xgcpolicy:optavgpause -Xms1024m -Xmx1536m -Xss512k Linux RedHat 7.3 2GB RAM 8192 File Descriptors JBoss 3.2.2 final + Tomcat 4.1.27
While upgrading our application from JBoss 3.2.2beta to JBoss 3.2.2 final, we seem to keep running out of memory. There is much more analysis to be done, but one major culprit was the new SNMP Adaptor. After ~12 hours with no one hitting the application, JBoss sometimes dies with: 20:20:03,127 ERROR [STDERR] java.lang.OutOfMemoryError: heap allocation failed 20:20:03,128 ERROR [STDERR] at java.net.PlainDatagramSocketImpl.receive(Native Method) 20:20:03,129 ERROR [STDERR] at java.net.PlainDatagramSocketImpl.receive(PlainDatagramSocketImpl.java:129) 20:20:03,129 ERROR [STDERR] at java.net.DatagramSocket.receive(DatagramSocket.java:701) 20:20:03,130 ERROR [STDERR] at org.opennms.protocols.snmp.SnmpPortal$Receiver.run(SnmpPortal.java:285) 20:20:03,130 ERROR [STDERR] at java.lang.Thread.run(Thread.java:568) 20:21:21,388 ERROR [STDERR] java.lang.OutOfMemoryError: heap allocation failed 20:21:21,389 ERROR [STDERR] at java.net.PlainDatagramSocketImpl.receive(Native Method) 20:21:21,389 ERROR [STDERR] at java.net.PlainDatagramSocketImpl.receive(PlainDatagramSocketImpl.java:129) 20:21:21,390 ERROR [STDERR] at java.net.DatagramSocket.receive(DatagramSocket.java:701) 20:21:21,390 ERROR [STDERR] at org.opennms.protocols.snmp.SnmpPortal$Receiver.run(SnmpPortal.java:285) 20:21:21,391 ERROR [STDERR] at java.lang.Thread.run(Thread.java:568) I removed the service over the weekend and the instance is still up. It looks like OpenNMS uses a lot of file descriptors: http://lists.opennms.org/pipermail/discuss/2003-April/027601.html Just an FYI for anyone having OutOfMemory errors. -- Chris Bonham President/CEO Third Eye Consulting, Inc.
