Re: Re: [opm] memory leak?

Hi again,

I moved forward to make tests and put the bot to work
with negcache set to 600 seconds. In 48 hours the bot
was using ~250MB.

Tests without negcache were using too much resources
and I didn't do them for long time. The FDs jumped
quite high and the bot was still adding quite a lot of
KB to it's memory every minute. In the evening when
the network had ~30K users, after 90 minutes of
working without negcache the bot had scanned 41584
connections and was using 81MB of memory. Is this
still normal? I would really like to limit the memory
the bot uses so I don't have to restart it every 48
hours when it had used most of the free memory of the
system.

I did also some tests with valgrind. It didn't report
anything. I did the tests with valgrind using negcache
and without it. Further, I suppose the many MBs in
memory are not linked to the caching of non-proxy
hosts. All I know is that there is definitely
something wrong.

Let me know if there is anything I can do further in
order to solve this issue.

ongeboren
