According to Miquel van Smoorenburg:

the problem is not INN but the kernel. 2.4 kernels have a lot of (known)
problems with memory management under stressed boxes.

I'd like to but it is difficult.. I'm not near this server and there's no
interesting information in the logs that I can use post-mortem.
Usually, I'm getting messages by phone from on-site people... not ideal
for ksymoops :(

that's what I feared.

thank you for the advice. I'll try a patched 2.2.19 if nothing else works.
