hi!

 

basically treads on linux-2.4 are cloned processes, hence the

large number of entries in ps.

 

this is no problem but works as designed, linux-2.6 will be different.

Hi Paul,

Yes I am running Linux: Kernel 2.4.18, is this a kernel process table problem or just how ps on Linux works?

Thanks and kind regards,

What platform are you running on. There is a known problem
with the way the Linux reports Java threads(each as its own
process). When actually  there are only a few java processes
running with alot of threads.
