instantaneous application instances on Solaris
Hi,
I have a java application running on a Solaris 9 machine
with Java 1.5.0_07.
I can see the instance of the application in the process list by ps command however once in a while it displays both the original and another instance but a child one this time with the same jvm arguments I assigned for the original one.
When I run immediately ps command again this child instance vanishes.
What can be the reason for this kind of behavior? Is there possibility that thread creation are displayed as actual processes.
Thanks in advanced

Can you post "ps" command and results?
You can try to send "kill -3" to the process periodically and look for a non-expected-thread on thread dumps.

Depending on your system configuration you will see lightweight processes for each thread instead of kernel processes.

Hi guys,Thanks for the answers.We've realized that some of the threads in the application hit enormous and unusual amount of CPU usage. As far as I抦 concerned it has to be fixed. By then I guess process list problem will vanish too.
