Sushil,
I think you meant to post this to the mailing list.

I can think of several things that could be happening to cause
the Wrapper to restart but I would be guessing without seeing
the log file.   Could you please set the wrapper.debug=true
property in your wrapper.conf file.  Then rerun your application.

Post back with the contents of the log file as an attachment.
Only send the log file about 5 minutes before the restart to just
after the new JVM has come up.   I should then be able to tell
you exactly what is happening.

A couple questions at the same time though.  Your max memory
is set to 512MB.  What is the total amount of physical memory
on that system.   Java behaves very poorly if the the JVM's
memory is forced to disk swap even slightly.  It is important to
make sure that you always have enough free memory to support
all of the JVM's memory.   I have seen cases where the JVM will
freeze for up to 5 minutes and run at at least 1/1000 normal
speed because of disc swapping.

Cheers,
Leif
