Try a 32 bit kernel if you can't upgrade the kernel to a new version.
It's a kernel bug, I'm pretty sure.

I can make you a skiplist from those files easily enough, but if you're
running a buggy kernel it won't help you any (besides, skiplist in 2.2
is buggy as all whatsit... and I can tell you the code in cyrusdb_flat.c
stinks too.  Whoever wrote this stuff must have done it before any of
the concepts like factoring identical code out into functions had been
invented!)
