Again DSO-mod_perl and leaking on restart: FreeBSD

[Alvar Freude <al...@merz-akademie.de>]

Hi,

some weeks ago here was the discussion about DSO-mod_perl and leaking; as
far as I understand it the solution was, that on SOME platforms (solaris)
mod_perl should be build as static.


It seems that FreeBSD is such a platform ;-)


I build Apache from the Ports-Collection with mod-ssl --
/usr/ports/www/apache13-modssl -- (with 1.3.20 and 1.3.22) and manually
Perl 5.6.1 (NO mymalloc, no compatibility, with mymalloc also tested) and
mod_perl 1.26 as DSO with APXS.


My mod_perl-Application has a global and resident hash, about 18 MB, which
is build in the startup-script.

At normal startup, it seems that mod_perl requires TWICE the amount of this
hash, and each restart (also graceful) it eats ~18 MB. 1 GB is fast full ;-)


The mod_perl from Ports Collection is build also as DSO and has the same
problem (with old Perl replaced by 5.6.1).


Has someone mod_perl on FreeBSD WITH DSO and without leaking running? If
not possible it might be good to include a warning in the Makefiles or
mod_perl-Guide etc. 

I prefer to build Apache from the Ports collection, so at next I'll try to
create a Port with static mod_perl ...


Ciao
