Hi George,
volumes are stored remotely on a file server; only the file daemon is
running on the mail server, and its files (only state and pid, if I
understand correctly) are under /var anyway.
I forgot to say that I've already checked the file lists without finding
anything suspect.
My feeling is that this should have something to do with that huge file
not being really identified as sparse, all available hints (including
size difference) point in that direction.
Thanks,
Alberto
