On a FreeBSD 4.3-STABLE box, I get about 9M per HUP.  This server is
running every page through Template Toolkit.  Apache is built from the
FreeBSD ports collection with mod_ssl, and mod_perl is built via APXS
from the 1.25_01-dev on Feb 8, 2001.

I guess it's time to pull out my debuggerizer hat. ;-)

1.21_01 had two dso fixes, one to close all .so's opened by DynaLoader and
one to call perl_shutdown(), both of which were large leaks.  with
1.25_01-dev and Perl 5.6.1 i see a 4k growth on the first kill -USR1 and

DSO mod_perl HUP memory leak

2001-06-14 Thread Paul G. Weiss 

I know that this is an ongoing problem, but I seem to remember that
someone somewhere had a patch that reduced the size of the memory leak on
restarts to a manageable size.  Has this patch been applied to the CVS
version?  If not, can some kind soul tell me where to find it?  I've
looked around the net in vain.
