tcpdump in vps not working after a while
I have some strange issue. I'm running pbs 5 2.6.32-042stab053.5 . After a while inside the vps'es tcpdump only captures outgoing traffic from the vps, not incoming traffic. On the hardware node monitoring venet0 it works fine. This happens both on venet or veth. This is the second time it happens. Last time it happend was fixed after a service network restart on the hardware node. This time seems that it doesn't work. Probably a reboot will fix it.
If anyone has any ideas on this one there are more then welcome.
Issue is only with capturing packets since packets do arrive on the vps just fine only not shown with anything that uses libpcap. I've tested on centos 5 32/64 bit centos 6 32/64 bit and same results.
