We are having this very strange issue on Squid cache server on FreeBSD, the server after few hours hangs up and give this error
2004/08/25 15:42:48| comm_udp_sendto: FD 6, 217.21.5.35, port 53: (55) No buffer  space available
2004/08/25 15:42:48| idnsSendQuery: FD 6: sendto: (55) No buffer space available
