[Clamav-devel] memleak in clamd (freebsd 5.4) ?

Martin Blapp Wed, 11 May 2005 02:04:01 -0700


Hi all,

On our busy mailserver we see clamd leaking mem like hell. I've now used valgrind to debug this a bit further.

We use ClamAV devel-20050511 on FreeBSD 5.4 release, but I have seen the memleak on the devel port since ever. After scanning 10'000 mails, clamd has grown over 100MB, after an hour it is 200MB big. I doesn't matter which threading library we use, it happens on both libc_r and libpthreads. The strange thing is that on average load during evening, the probem doesn't happen. Only if we get a lot of mails (3-5 per second), the problem shows up.

Now to the valgrind output:

record 26 I, and record 24 in II seem to be normal, those are the cached virus-databases.

But what about record 25 in I and recore 26 in II ? This seems to be the responsable place for the leak. But looking at the source I can't find the leak which is responsable:

textDestroy(text *t_head)
{
        while(t_head) {
                text *t_next = t_head->t_next;
                if(t_head->t_line)
                        (void)lineUnlink(t_head->t_line);
                free(t_head);
                t_head = t_next;
        }
}

looks quite normal to me. Any obvious bug here ?
