Hello,

as probably mentioned already, first try to do an update to a maintained version (e.g. 5.3.6).

Try the steps descriped at “monitoring memory” in this wiki page: https://www.kamailio.org/wiki/tutorials/troubleshooting/memory

Especially look out for increases in one of the module or core section(s).

If you find out that it keeps growing in some area, after you have done an update, open an issue on our tracker.

Cheers,

Henning

Hi Alex, It happened after 3 to 4 days of restart and happen in peak hours, but the load is not too high less than 100 calls.

Thanks

Does this happen immediately, or some time after you restart Kamailio? During peak traffic loads? Randomly?

Hello,

the 5.1.2 is old, unmaintained at this moment, but you should always run the latest version in a series to be sure you are not affected by bugs fixed already. For example, in this case you are in 5.1.x series, so you should run 5.1.10. But it is better to upgrade to a maintained series, like 5.3 or 5.4.

Back to 5.1.x, after upgrading to 5.1.10, you can also set mem_join=1 in the config file, that can help in such situations, provided that to allocated enough shared memory for the traffic you are handling. In newer release series of kamailio mem_join is 1 by default, but not in 5.1.x.

Cheers, Daniel

Hi,

You can check statistics of shared memory on Kamailio. In this way, you can decide whether you need to increase your shmem or not..

Type "kamctl stats shmem" on cli of Kamailio server and share the output..
