Re: VSZ keeps on increasing as threads created and cancelled on rhel3.0

I am observing this with RHEL3.0. Any information about a patch/update
that fixes this for RHEL3.0 would be appreciated..

Linux 2.4.21-4.ELsmp #1 SMP Fri Oct 3 17:52:56 EDT 2003 i686 i686 i386 GNU/Linux

I used to see something similar on my machine running regular 2.6
kernels and glibc from cvs. It stopped some time ago though.
Supposedly some bug has been fixed.
