Perl leaks memory on long running tasks - this is the nature of the
dynamic memory management of Perl.
If the 'lib/AsspSelfLoader.pm' is installed the graphs will look like
there is some leaking memory - in this case, assp starts with a minimum of
compiled code and allocated memory in every thread, if any additionaly
code is required, it is compiled at runtime and the required memory is
allocated (and never given back to the OS !).
>When assp starts, it use ~ 400 MB, which looks like a reasonable value

This is OK.
> 9 workers
this is too high - five should be OK ! Than more workers - than more
memory fragmentation !
on 32 Bit Perl and five workers anything below 1GByte memory usage is OK
on 64 Bit Perl and five workers anything below 2GByte memory usage is OK
Than higher the Perl version , than less memory usage - ~ 10% per Perl 5
major version step 10,12,14,16 - and less memory fragmentation!
>I cannot restart assp per some interval.
So Perl will fragment your RAM, will allocate more and more memory - and
will CRASH , there is no question 'if'; but only at what time !
At least one restart a week should be possible.

Betreff: [Assp-test] memory leaking
Hi,
I've memory leaking on 2.2.2, 12352 (in fact I had the same problem with
older versions too).
assp can work a day, and all of a sudden start to leak, or work more
than a week, and start leaking - you can see that in attached graphs.
Thought that may be rebuildspamdb related issue, so I've disabled it for
a week or so. But memory is still leaking.
Next, I thought there is some plugin that leaks, so I've disabled a few
of them I don't use. No OCR, AFC, ARC active plugins.
Perl modules are fresh.
Looking into logs at a time when memory usage is raising, but didn't
find anything worth.
Anything else I should look into ? Or any advise why it might leak ? I
cannot restart assp per some interval.
When assp starts, it use ~ 400 MB, which looks like a reasonable value
to me.
Using perl-5.14.2 (i86pc-solaris-thread-multi, solaris-10, 32b), no flat
files, using mysql/innodb, 9 workers (~ 50k messages per day).
Thank you.
