Question

We are facing the below problem at our production enviournment in unpredictable manner sometimes the server is down in a day or sometimes in a week, below is the exact error dump, below are the settings for the server.

JDK: jdk1.6.0_21
Server: Tomcat 7.0.2
OS: Red Hat Enterprise Linux Server release 5.5

In catalina.sh the following setting has been done:

JAVA_OPTS="-Xms1024M -Xmx1536M -XX:+HeapDumpOnOutOfMemoryError -XX:+AggressiveOpts 
-XX:-DisableExplicitGC  -XX:AdaptiveSizeThroughPutPolicy=0  
-XX:+UsePSAdaptiveSurvivorSizePolicy 
-XX:+UseAdaptiveGenerationSizePolicyAtMinorCollection  
-XX:+UseAdaptiveGenerationSizePolicyAtMajorCollection -XX:PermSize=768M 
-XX:MaxPermSize=768M    -XX:+PrintGCDetails -Xloggc:/tmp/gcLogs.txt"

export CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=22222 
-Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.password.file=/jakarta-tomcat7/apache-tomcat-7.0.2/conf
/jmxremote.password -Dcom.sun.management.jmxremote.access.file=/jakarta-tomcat7/apache-
tomcat-7.0.2/conf/jmxremote.access"

Answer 1

For the record (and Google), this looks like both these bugs, which were fixed in the 1.6u22 release of sun's jdk. So, first thing to do is update your JVM. If it still happens, and always happens on a particular method, you can exclude that method from compilation (as long as you're aware of the performance implications of that) with the following jvm flag:

-XX:CompileCommand=exclude,org/apache/velocity/runtime/directive/Foreach,render

(as suggested here). But, first update your jvm.
