I'm running a number of containers for VoIP traffic, and I'm having a certain amount of trouble with those which are running FreeSWITCH. Interestingly, one running Asterisk with about the same amount of traffic is working fine.
What happens, after a while, is that the container's networking just stops. Name resolution ceases; attempts to ping the outside world (by IP or hostname) fail, tshark within the container shows no network traffic in or out, tshark on the host node's Ethernet interface shows packets inbound to the container, but nothing emanating from it.
The beancounters show overruns on tcpsndbuf, tcprcvbuf and dgramrcvbuf.
Restarting the container fixes the problem for a while - typically about 24 hours.
The host's running x86_64 kernel 2.6.18-238.9.1.el5.028stab089.1
Any ideas, pointers, or things to take a look at greatly appreciated.
