Java SE (Java Platform, Standard Edition)

Hi all

We have a production application running on WebLogic 8.1 SP4 that has recently been crashing out giving the below error. We've tried adjusting our JVM settings from

JAVA_OPTIONS="-Dnetworkaddress.cache.ttl=60 -Xms2048M -Xmx2048M -XX:NewSize=512M -XX:MaxNewSize=512M -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -Xloggc:gc.log"

to

JAVA_OPTIONS="-server -Dnetworkaddress.cache.ttl=60 -Xms2048M -Xmx2048M -XX:NewSize=512M -XX:MaxNewSize=512M -XX:MaxPermSize=256m -XX:+UseParallelGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -Xloggc:gc.log "

as we believed the problem might lie with the CMS collector since the system bailed out whilst performing this type of collection but the system has since crashed with the revised arguments. Anyone encountered the same error?

The tail end of out gc.log reads
