Hi,
We use kamailio as a router in our PBX server. The test below causes
significant decreasing of free shared memory and
many "out of memory" errors in kamailio log:
Preconditions: kamailio server with 256Mb of shared memory allocated.
Test actions: run two load testing scripts at the same time:
1) 10000 register operations;
2) 20000 calls (about 300 per sec);
Results:
1) memory consumption in peak values:
- shmem.free_size: 1.8Mb
- core: 120Mb:
- build_req_buf_from_sip_req: 12.5Mb
- msg_lump_cloner: 23.6Mb
- sip_msg_shm_clone: 84Mb
- tm module: 118Mb
2) shmem.free_size parameter back to normal after the test, so it could
be concluded that we don't have any memory leaks.
Is it normal behavior or it's possible to do something to increase
performance?
PS: the same behaviour occurs for various values of shared memory defined
at the start of kamailio server (128Mb, 256Mb, 512Mb etc.).
Thank you,
Andrey

New subject: Free size of shared memory falls to near zero during the load testing
Hello,
if you run with 512MB, is the shm free getting to 1.8MB as well for same
figures of registrations and calls?
Cheers,
Daniel

Andrey,
Can you please run “kamcmd tm.stats” and check the values. I have a similar problem and
see clearly
a lot of transactions not being freed, eating up memory and ending with out of memory
messages in the log.
Have an open issue about it in the bug tracker.

Daniel,
I've repeated the test with 1Gb of shared memory (-M 16 -m 1024). free_size
parameter fell to 2Kb during the test.
Olle,
I've gathered metrics about tm module:
- tm.build_cell: 490Mb at the on the peak;
- other metrics take about 2Kb - 6 Mb
Thanks,
Andrey

My understanding is that used memory goes back to normal after the test,
not something that stays high forever, so it doesn't look at all with
what you refer to.

New subject: Free size of shared memory falls to near zero during the load testing
I've increased shared memory to 2Gb (-M 16 -m 2048). The free_size
parameter was not less than 793Mb during the test. It seems that 2Gb is an
optimal value for my setting.
Daniel,
Yes, you're right. That was not a memory leak, I think that this is about
amount of memory required by kamailio for the specific test case.
Thanks,
Andrey
