Are you running a 64 bit kernel?

(just wondering - we have hit pretty much the same issue - and were
wondering about dodgy kernel issues being a proble - it's only one
machine that seems to have corrupted seen files, only on replicas)

We've been running 2.3.12 for about a week, and it's only last night
that we had anything funny show up at all.

Interestingly, it's probably the first time cyr_expire ran on 2.3.12
just before that - and also the first time our check-replication
script was running, which loads a lot of seen files on BOTH ends.
