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

Subject: Re: [SR-Users] Getting memory error on kamailio v5.1.2 tm:Free fragment not found!

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

Hello,

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