Hi,

I'm currently trying to use a Daemon which was originally written for unix.

It seems as if there are several memory leaks in the daemon's source code but I'm unable to detect the objects that are causing them. That's sort of a big issue since the daemon is using more and more memory if running for several hours.

The script I'm talking about is called SpamAssassin, with its Daemon "SpamD". I'm using ActivePerl (5.8.9.827).

I've tried to identify the problem by using the Devel::Leak::Object package, but not really sure how to use it. This is what I got when leaving the script:

I've already tried to weaken some references, but as I'm still a novice in Perl, it didn't led to a satisfying result.



Any hints on this?
