dgramrcvbuf saturation when using Centos 6 [message #49751]

We are trying to migrate our software from centos 5 to cent os 6 and we encounter a strange issue:

We create new OpenVZ container using centos 6.4 official Template (64 bits). We run asterisk in these container. Under certain call cases (call transfert) the dgramrcvbuf counter hits the limit and causes UDP packet to be dropped. Once the limit is hit the only way to restore the situation is to restart asterisk.

We tried to increase the limit but under this call case, dgramrcvbuf saturates almost instantly.

On the same node, centos 5 containers are not subject to the same issue. Has anybody spotted such a problem already ?

Kernel used:

2.6.32-19-pve #1 SMP Wed May 15 07:32:52 CEST 2013 x86_64 GNU/Linux
