[SR-Users] Kamailio 1.5 stops processing messages

Hi,

It happens randomly, after some hours or some days, no particular pattern.
There is no error message in the syslog. The debug level is set at 0. Would
a higher debug level help to track the issue?
We only use t_replicate to send the REGISTER to a backup proxy.

Thanks,

Santi
