[SR-Users] Bad File Descriptor

[David J.]

  5(20390) ERROR: <core> [udp_server.c:586]: ERROR: udp_send:

I see this error when I try to restart kamailio after crash; I see the 
cause of this problem is 'stale' entries in the location table;

If I delete this entries kamailio starts fine; any suggestions to 
prevent this from continuously happening.

Thanks.
