Anyone else seen something like this? The only FS that was corrupt was
/var, which leads me to believe that its a sendmail problem, as
/var/mail is it's own partition. Usual stuff (pop3, imap, sendmail)
running on this box and nothing else.
Any help or advice on how to stop this appreciated. Thanks,
Gary
