This isn't /var, but /var/mail on a separate file system on a
separate drive. No log files, nothing but inboxes (and those
dot files that qpopper creates).
I have not tried fsck. The next time this happens I will do that.
I cannot unmount /var/mail, the system claims it's in use.
By what? I donno.
I agree I shouldn't have to reboot this thing, but couldn't otherwise
fix the problem.
