Hello,

Quote:


-Out of desperation I turned off iptables entirely (no rules, no modules loaded)
on both the HN & VPS, which appeared to clear up everything.
-The issue reappears with iptables turned ON on the HN but turned OFF on the VPS
(IPTABLES="" in /etc/vz/vz.conf).


Sorry, I didn't catch you. Why doesn't this mean that the problem is because of the iptables rules on the HN?


Quote:


tcpdump (same thing seen on HN and VPS)


Are you sure that we get exactly the same output inside VPS?

Is there anything in logs or in dmesg?

could you please attach the full output of /proc/user_beancounters?
And please attach the output of the following files:

- /proc/net/netstat
- /proc/net/softnet_stat
- /proc/net/snmp
- /proc/net/sockstat

but not as is. Could you please collect information in the dynamics i.e. when a problem appears collect information to obtain what changes and what kind of errors increase.

P.S. You'd better attach the requested information to your bug report instead of attaching here.
