Hello!

We get the following message quite often on our hardware node:
kernel: TCP: time wait bucket table overflow
Another Thread/Message that describes this problem can be found here:
http://forum.openvz.org/index.php?t=msg&goto=7066
The problem is that there is no answer that could help solving the problem.
Maybe now is the right time to solve that problem. Wink

What I want to know is whether that message is important or not. Maybe someone can also give an advice on how to solve that problem.
btw. Our hardware node is under high load (cpu wise and traffic wise) and only runs on VE.
I can provide as many configuration information as you want.

I really hope someone can help us fixing that annoying problem.

Thank you

Bernhard

I'd like to bump this issue. We're running 2.6.18-ovz028test007.1-smp, and seeing lots of the same message.

High traffic box, but not particularly high cpu.

A problem we're seeing alot is if any vz hits it's tcprcvbuf limit, and failcnt's on that parameter, the entire box (hw node) will not accept any tcp connections (i.e., ssh into my hardware node), and has to be bounced.

Anyone seen similar issues, regarding tcp sockets in any way, and how you might have tuned this better?
