As Knut said, that size should be plenty. I'd look to see if you have some kind of memory leak. Take a look at either the heap section of Resin's PDF or /resin-admin. Specifically look for the ZombieClassLoaderMarker. > >> <jvm-arg>-J-server</jvm-arg> >> <jvm-arg>-J-d64</jvm-arg> >> <jvm-arg>-Xms3000M</jvm-arg> >> <jvm-arg>-Xmx3000M</jvm-arg> >> <jvm-arg>-XX:MaxPermSize=250M</jvm-arg> > I could increase the -Xmx property, but I am wondering if there is a > better property to tweak. > > I am also seeing the following warning messages: > >> WARNING com.caucho.health.analysis.AnomalyAnalyzer AnomalyAnalyzer >> JVM|Thread|JVM Blocked Count WARNING >> WARNING com.caucho.health.analysis.AnomalyAnalyzer AnomalyAnalyzer >> JVM|Thread|JVM Runnable Count WARNING > Does anyone have some advice on how to resolve these warnings?

If it's a little spike (2-3 threads), it's not a big problem, but if there are lots of threads in that spike you might have some kind of locking issue. -- Scott > > Thanks for your help > > Keith > _______________________________________________ resin-interest mailing list [email protected] http://maillist.caucho.com/mailman/listinfo/resin-interest
