Thanks for the reply. I actually have been following the directions on
http://www.opensips.org/Resources/DocsTsMem
Perhaps my memory is building up because I am receiving a ton of the
following in my PUA database table
mysql> select * from pua;
+--------+------------------+----------------+-------+---------+-----------------+------+------+----------+-------------+--------+---------+--------+----------+------+--------------+---------+----------------+---------+---------------+
| id | pres_uri | pres_id | event | expires |
desired_expires | flag | etag | tuple_id | watcher_uri | to_uri | call_id |
to_tag | from_tag | cseq | record_route | contact | remote_contact | version

This is because of the following function in my opensips.cfg script
dialoginfo_set(); (using this so I can have the BLF feature)
When I comment this out my script appears to run fine when I stress test it
with SIPP. I have the following
children = 10
Server has 1 Gig of RAM
I configured my config.h to be "define PKG_MEM_POOL_SIZE 4*1024*1024"
I execute the Opensips service with 128M of memory
I run my SIPP test for about 5 minutes and 30 seconds and get the following
outcome
Counter Name | Periodic value | Cumulative value
-------------------------+---------------------------+--------------------------

With this test I have nothing in my PUA table. Also at the end of this test
I see that I have the folllowing when I execute the "top" command
Mem: 1022536k total, 785916k used, 236620k free, 29708k buffers

Then I run a second test with SIPP and get the following
Counter Name | Periodic value | Cumulative value
-------------------------+---------------------------+--------------------------
Elapsed Time | 00:00:00:000 |
00:13:35:590

And then when I do the "top" command again I see the following
Mem: 1022536k total, 675176k used, 347360k free, 30956k buffers
Swap: 2097148k total, 0k used, 2097148k free, 345944k cached

18653 opensips 20 0 281m 2320 88 S 0 0.2 0:01.06 opensips
So a lot of the opensips processes have about 2.9% memory. I wait more
than 20 minutes to see if the memory would be released but it didn't.
Not sure if this is a bad thing or not. I could let my SIPP test just keep
running to see if OpenSIPS crashes from no memory if the memory keeps
creeping up or I could do a "kill -SIGUSR1 18643" to see what is currently
using the memory? Any thoughts or is this not an issue at all?
