Re: [Wrapper-user] how to identify and monitor different java-processes

[Leif M. <lei...@ta...>]

Jeroen,
To be clear, you have 20 Wrappers and 20 JVMs on the same machine?

Do have any idea whether it is the Wrapper or a Java process that is
leaking? or is that what you are asking?

What version of the Wrapper are you using?  There are a few known leaks in
older versions.

There is an undocumented feature that works on Windows that will log the
memory stats of the Wrapper and its Java process at regular intervals.
This might help depending on the nature of the leak.
wrapper.memory_output=TRUE
wrapper.memory_output.interval=60

You can also try the perfmon tool to track the process memories over time.

Please follow up with what you find out.

Cheers,
Leif
