[OpenSIPS-Users] udp send fail randomly

[Govindaraj, Rajesh]

Hi Opensips forum members,

This is very hot issue in our production. Please share any inputs that help to resolve the same.
Tried all the items listed on internet search like,


-          Check for nf_ct_sip module is present and any syslog error logs. It was not the case.

-          So many active sip sessions with remote end is fine with keep alive going on. So can rule out firewall configs as well. Just this random error atleast one per day.

Thanks,

Hi,

In of our production environment, the below error is seen once every day. There is no firewall rule changes in the system.
This issue never occurred in lab systems.
