Hi List,
I'm facing a memory usage issue with OpenSIPS 1.9.2 on a
Debian 7 server
root@asbc2:/home/kemathy# uname -a
Linux asbc2 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u2
x86_64 GNU/Linux
root@asbc2:/home/kemathy# opensips -V
version: opensips 1.9.2-notls (x86_64/linux)
flags: STATS: On, USE_IPV6, USE_TCP, DISABLE_NAGLE,
USE_MCAST, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_F_MALLOC,
FAST_LOCK-ADAPTIVE_WAIT
ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144,
MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535
poll method support: poll, epoll_lt, epoll_et, sigio_rt,
select.

main.c compiled on 11:15:37 Jun 20 2014 with gcc 4.7
The server handles something like 70000 to 90000 calls per
day, with around 20 to 40 Calls Per Second
As you can see on the following Cacti graphs, system's free
memory decreases constantly to finally reach the lower value
of 160M :

The system can stay 2-3 days working in this state, but for
example, yesterday evening (2014-06-25 18:50:00), opensips
crashed, after showing those log messages :
Jun 25 18:51:18 asbc2 /usr/local/sbin/opensips[11390]:

And after the service's restart, everything was OK :
Jun 25 19:12:39 asbc2 /usr/local/sbin/opensips[29351]:
INFO:core:main: using 64 Mb shared memory
Jun 25 19:12:39 asbc2 /usr/local/sbin/opensips[29351]:
INFO:core:main: using 4 Mb private memory per process
For information, here are the memory values at this moment;
opensips has handled 5000 calls since his bootup :
root@asbc2:/home/kemathy# free -m
total used free shared buffers
cached
Mem: 16082 12887 3195 0
339 11393
-/+ buffers/cache: 1154 14928
Swap: 32755 0 32755
For now, OpenSIPS is launched with S_MEMORY = 64 and
P_MEMORY = 4
My first idea would be to increase the P_MEMORY value to 8
for example, as it seems to be a lack of PKG Memory, but in
case it's a memory-freeing problem, it'll not solve our
issue (I think).
My questions are : How can we calculate the appropriate
value for S_MEMORY and P_MEMORY ? And how can we solve our
"out of pkg memory" problem ?
If you need further informations, or anything else, feel
free to ask me !
Thanks a lot for your help,
