(was: mod_perl DSO leaking on restart)
ah ha, right, since i always have PERL_DEBUG=1, perl_destruct_level is
always set to 2. good find! it should always be 2 for dso,
this patch
seems to fix USE_APXS too.

Doug,
Will this patch make it into 1.26?
yes.
If so, is there a slated release date for 1.26?
soon-ish. you can always configure: PerlSetEnv PERL_DESTRUCT_LEVEL 2
in the meantime.

i mentioned earlier in the thread 5.005_03 has leaks. although,
I think I've found the error of my ways.
The reason that it was leaking with a static build was that the
PerlFreshRestart directive was set to 'On'. This resulted in a
leak of a couple of Mb.
The reason that it was leaking with a USE_DSO build was that I didn't set
PERL_DESTRUCT_LEVEL. Once I

Doug,
I'm confused as to how you managed to *not* leak when I'm still
leaking. I've tried these tests on both a Solaris 2.7 system and
a Linux 7.1.
Here is a summary of what I do:
I build Perl
./Configure -des -Uusemymalloc -Dprefix=$(echo ~/test/prefix) -Dcc=gcc
make make test make
Now I'm really confused. I built the whole thing statically and it still
leaks:
the static build (using the same Perl):
~/test/prefix/bin/perl Makefile.PL EVERYTHING=1 \
APACHE_PREFIX=$(echo ~/test/prefix/apache) \
APACHE_SRC=../apache_1.3.19 DO_HTTPD=1
Now it still leaks 520K per
Don't be so willing to bet. Still leaking.
I did as you said and just rebuilt Perl and mod_perl but didn't bother to
rebuild all the Perl modules (I would have done so had I been successful
here).
Here's what I see:
make start_httpd_fork
../apache_1.3.19/src/httpd -f `pwd`/t/conf/httpd.conf

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

ok, here's why i kept asking for perl -V. i don't see Perl's malloc.c

Still leaking I'm afraid, by roughly the same amount.
I'm posting the files you asked for. Perhaps it has something to do with
the fact that both the Perl and Apache are installed in non-standard
places, or that I'm also using mod_ssl.
Here goes:

Same here. I did a few graceful restarts and the usage jumped to 80M from
10M... Then I apachectl stop and apachectl start to get a clean
restart, it works fine.
I am new to this list. Maybe this problem has been addressed...
