[Serusers] SER stops for some reason

[Bo]

Hi,

I have been running SER for a long time without any problem. But today it stopped by itself and I found the following messages in the syslog.

Mar  4 11:55:40 sip ser[891]: ERROR: udp_send: sendto(sock,0x40319580,734,0,0x4034c30c,16): Invalid argument(22)

Mar  4 11:56:07 sip ser[876]: core was not generated
Mar  4 11:56:07 sip ser[876]: INFO: terminating due to SIGCHLD

What may be the possible cause? How to avoid it?

Thanks a lot!
Bob
