Server crash after LIST_DELETE in Log

** Low Priority **

Hello,

 I have a strange Problem with (I guess) the Netfilter. I have a Proxy-Server running, that is dual-homed with a transparent Squid on one Interface listening. After some time, the syslog lists these messages:

Mar 24 15:36:18 Proxy kernel: LIST_DELETE: net/ipv4/netfilter/ip_conntrack_core.c:299 `&ct->tuplehash[IP_CT_DIR_REPLY]'(e96c0d64) not in &ip_conntrack_hash[hr].
Mar 24 15:36:39 Proxy kernel: LIST_DELETE: net/ipv4/netfilter/ip_conntrack_core.c:299 `&ct->tuplehash[IP_CT_DIR_REPLY]'(dd67fd24) not in &ip_conntrack_hash[hr].
Mar 24 15:36:55 Proxy kernel: LIST_DELETE: net/ipv4/netfilter/ip_conntrack_core.c:299 `&ct->tuplehash[IP_CT_DIR_REPLY]'(dc976864) not in &ip_conntrack_hash[hr].

5 seconds more...
and the server freezes...

Sometimes the machine runs well for a whole week, sometimes a few hours.

I've googled around for it, and saw some other people having equal Problems, most of the time with older kernels.

The Hardware I use is a Compaq ProLiant DL 380, OS is S.u.S.E Linux 9.0 with a self-compiled 2.63 Kernel, and iptables 1.2.9. I've had earlier versions of iptables & Linux running, but the Problem stayed the same.

It'd be really nice, if someone's got a clue about that.

Best Regards and thanks in advance for any hints.

björn
