Hello,

the usual suggestion is to first upgrade to a supported version, as 5.5.x is end of life. Please upgrade to e.g. 5.8.1 version. You will need probably a bit of kamailio cfg adaptions and maybe some DB script adaptions.

Cheers,

Henning

Subject: [SR-Users] Kamailio crash due to UDP receiver child (kamailio 5.5.5)

Hi,

The kamailio version we are using is "5.5.5", We are facing a kamailio crash issue recently and it has generated the core-dump. Based on the core-dump analysis we could see that "si_desc = "udp receiver child=3" getting crashed. We could see the below error in the core-dump trace,

#22 0x0000562c33524750 in udp_rcv_loop () at core/udp_server.c:543

tmp = 0x1150955ff0 <error: Cannot access memory at address 0x1150955ff0>

Please suggest how to fix this and your inputs will be appreciated.

Note: Due to confidentiality, I'm not able to share the core-dump trace.

Thanks.
