Bogdan,
I'll need to check out the shmem statistics.
I mean, this is the memory output for the OpenSER processes having run
for about 24 hours. Does it look right?:
# ps -C openser -o vsz,rss
VSZ RSS

Here are the modules I'm using. Not sure if any have a dependency on libxml:
loadmodule "mysql.so"
loadmodule "sl.so"
loadmodule "tm.so"
loadmodule "usrloc.so"
loadmodule "auth.so"
loadmodule "auth_db.so"
loadmodule "maxfwd.so"
loadmodule "mi_fifo.so"
loadmodule "nathelper.so"
loadmodule "perl.so"
loadmodule "registrar.so"
loadmodule "rr.so"
loadmodule "textops.so"
loadmodule "uri.so"
Thanks,
Julian

Hi Julian,
Have you tried to use the the shmem statistics to monitor the usage of SHM
memory?
Both for PKG and SHM memory, openser allocs at startup the whole memory
(depending of how much you configured). Any leak will not be vizible for any
external tools.
Also, are you using any module that have dependency of libxml library?
The dump you posted shows more or less nothing more than init phase -
before sending the signal, be sure you select a worker process (use fifo
command "ps" to get the list and types of processes).
Regards,
Bogdan

Henning,
I don't get any memory allocation errors.
I've recently updated to OpenSER 1.3 branch SVN r4107 but the 'leak'
still remains.
On a 4GB box, free memory just seems to deplete.
I have a cron job which restarts OpenSER every night but it seems like
not all the memory is free'd up. Eventually the box needs to be
rebooted. In the past, running out of memory has led to oom-killer
killing OpenSER.
For example, I have this cron job:
*/5 * * * * root echo "`date` `free | grep 'buffers/cache'`" >>
/var/log/free_memory.log
Memory just depletes. Here's where OpenSER was restarted around midnight:
