Hello, Does this happen immediately, or some time after you restart Kamailio? During peak traffic loads? Randomly? -- Alex On 9/8/20 4:53 PM, M Arqum CH wrote: -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users

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 On 08.09.20 23:06, egemen ulus wrote: 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.. Regards Egemen U.
