In the meantime, the environment has been much more stable than it was before the move to Java 6 and the new JVM options. However, a few minutes ago, Tomcat became completely unresponsive, while the CPU usage was very low (~3%). This was on our external server, with these options:
-Djavax.sql.DataSource.Factory=org.apache.commons.dbcp.BasicDataSourceFactory -Dcom.sun.management.jmxremote -XX:MaxPermSize=512m -Xloggc:D:\logs\gc\tomcat-gc.log -XX:+PrintGCDetails -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+DisableExplicitGC -XX:NewSize=3072m -XX:+UseCompressedOops -Xms7168m -Xmx7168m The gc log is showing a lot of activity during the unresponsiveness (the gc log is attached to this message). Do you guys see any clues? Thanks in advance!
