Description cdent 1999-03-19 06:56:08 UTC
It appears that the mod_perl shipped with secureweb
has a memory leak when configured as a DSO that can
be demostrated on a server that has the mod_perl
module included but doesn't actually call any perl
by hupping the server while watching the process
size. The mod_perl version grows considerably faster
than the non-mod_perl version.

I've tried a few different combinations:

perl 5004_01, perl 5004_04, mod_perl 1.16, 1.16_02,
1.18

This is all with redhat 4.2

I've read that it may be better to make mod_perl not
be a DSO but have it in the binary instead. Some of
the folks on the mod_perl list claim that helps.
This is inconvenient for you folks but perhaps you
would consider shipping the rpm either with two
binaries or in two flavors?

mod_perl 1.19 still has this memory leak.  I am discussing things with
the developers.

I'm seeing major problems with busy servers without using mod_perl,
too.  My httpsd processes are growing to over 50 megs total size
pretty quickly if they see significant load.

The one test server I had with mod_perl included grew to over 150 megs
without any load at all.  Any progress on this?

Comment 3 Preston Brown 2000-01-13 04:46:59 UTC
the concensus among mod_perl people seems to be to restart the server
periodically in a cron job if you are experiencing memory leaks.  While the
problem may be fixed in a better way down the road, this is the current
solution, and while sub-optimal, it works.
