hello I have
windows 7 64 bit with 8 gb memory
I have java 1.6 as 32 bit apps (we have a lot off dll that 32 bit
my problem
I run my apps with
-xms=500m -xmx=500
the apps run with 250mega the task manager show 400 mega
I try yourkit and I do not found the problem
the heap use is 250m the permsize is 65m
so how the task manager show 450m
in the time that I work with the apps the heap size +perm size get together to 400m
but in the task manager the commit memory of java 1.4g
and then the jvm is cursh
how did I can fix or found what my probelam

Re: memory probelam
The JVM uses memory outside the heap and non-heap memory pools:

In particular, the 32-bit dlls you mentioned likely allocate native memory.
To provide detailed analysis, we need:
- the crash detail: the crash log file hs_err<pid>.log
- the profiler agent log file <user home>/.yjp/log/<session name>-<pid>.log
Please send them to [email protected] if you cannot share them in the public forum.
