Continuous 'netstat -sp udp' with 100 ms. interval shows dropped UDP due to full socket buffers sometimes. The script also monitors 'netstat -anp udp' and there are no connections with non-zero Recv-Q value by the end of the interval with drops. The server is used as SIP server (ser) with RTP proxy (rtpproxy). Avg pps (Broadcom BCM5721 Gigabit Ethernet, bge): 630 in, 460 out. Any ideas how to find out a reason? (no kernel changes allowed, the server is in production) -- tut DaRK VoIP GuRU
