Hi,

I had upgraded Kamailio from 5.4.7 to 5.5.5, Then I restarted the Kamailio service.

After upgradation im getting the below error, 

/usr/local/sbin/kamailio[21754]: ERROR: <core> [core/udp_server.c:596]: udp_send(): sendto(sock, buf: 0x7f7502289200, len: 61012, 0, dst: (10.122.45.189:5080), tolen: 16) - err: No buffer space available (105)
