Hi,

The message you refer to was mine. Turned out there was a bug in the
handeling of icmp (port unreachable) packets from clients. It was fixed in
2.6.12-rc5 (iirc). I don't know if the problem and fix applies to 2.4.

Did the memory usage grow slowly, or explode overnight? (Until you run out
of memory you prolly wouldn't notice unless you monitor memory usage.)

Rgds,
Mark.
