Hi Squid Users, I have a server running Debian Squeeze and Squid3 (version 3.1.6 from Debian repo). It is configured using winbind+ntlm for authentication. The server ran fine for a while now (I'd say 6 months more or less) but now I get a lot of "TCP: time wait bucket table overflow" errors in syslog. After ~30 minutes the system then begins killing processes and reboots. First I thought that the problem was that the server had not enough RAM. I upgraded from 512MB to 1GB but the problem still existed. Then I controlled on the VMware Host (the server is a virtual machine running on a ESX Cluster) about the performance datas and I saw that performance was not the issue (Memory, CPU and all the other counters are at 30% max.). About 50 people are using that proxy Server. There are no other services running on that Server. It's just squid3, samba (for winbind) and apache (only hosting the proxy.pac).

Thank you in advance. Christoph Fink
