It is just default on my absolutely standard deployment system for WO (Xserve G4 , 2GB, MacOS X 10.5, Java 1.5.0_24)
I found this 64M doing ps ax | grep "java" It lists all WO apps like this: /usr/bin/java -XX:NewSize=2m -Xmx64m -Xms32m -DWORootDirectory=/System ... So as I understand "-Xmx64m" - that is maximum heap size. Actual memory usage for whole JVM is about 300M. >> So my question is - what should I do now? >> Is it expected behavior for large WO application? > > Using 64M+ of memory is, the increasing heap size is not.

Most exceptions I get now are cased by "java.lang.OutOfMemoryError: Java heap space" So that is what I am trying to get rid of. I get any other exceptions not more often than once a month whereas OutOfMemoryError comes nearly every 5th day =( > Also check that your session sleep(), awake(), and terminate() can never > throw an exception. Would I see such exceptions in log if they happen? I did not see any yet. > Beyond that, I would try a heap analyzer to see what the objects are that do > not get collected. What is "heap analyzer" ? And where can I get it? Gennady _______________________________________________ Do not post admin requests to the list. They will be ignored.
