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,

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).

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:

Julian,
how much private and shared memory are you using and how many process
you have?
Again, note that openser is not dynamically getting memory from OS at
runtime - all memory that is used by openser is requested from OS at
startup.

Hi Henning,
Thanks for the hint.
So, your openser processes should use as private memory:
(8/*udp*/ + 1/*timer*/ + 1/*attendant*/ + 1/*fifo*/) * 1 = 11M
So, overall, all openser processes will use 11 + 128 = 139M plus memory
requested directly from the OS.

it is clearly that you have 8 workers (2 - 9) - the rest of the

the system.
For the workers, I guess there are some script function (from some
modules) that are directly requesting memory (and not via openser mem
manager). Looking at your list:

there are none of the modules that use libxml2 or expat, but I see you

what about mysql? It uses the mysql library which probably will use OS
memory allocator and not openser's memory allocator.

New subject: [OpenSER-Users] [OpenSER-Devel] Memory dump for OpenSER 1.3.1 which slowly leaks memory
Hi Klaus,
I discarded the mysql option as a potential problem as in this module,
all the mem ops are transparently done by the mysql client library - as
a user of the lib, there are very small chances to screw up something
that will lead to mem leak, without having worst side effects (like out
of sync errors).
On the other hand, libxml2 give you (as user of the lib) more
flexibility in playing with data (xml and attr nodes), so the chance to
get a undetected leak is much, much higher.

it is clearly that you have 8 workers (2 - 9) - the rest of the
processes have a similar VSZ and RSS, so no more mem is required form
the system.
For the workers, I guess there are some script function (from some
modules) that are directly requesting memory (and not via openser mem
manager). Looking at your list:

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"

there are none of the modules that use libxml2 or expat, but I see
you are using perl - there were some past problems with mem leaks due
this module, so you may try to take out the module and see if the
leak is still present.
what about mysql? It uses the mysql library which probably will use OS
memory allocator and not openser's memory allocator.
