I assume you do have a full fsck done on the filesystem after you see
these errors?

If an fs check is getting suggested by ext3 during the mounting of the
disk, then your boot scripts must not be set up correctly, or
/etc/fstab has been set up to disable fsck getting run automatically
on said filesystem.

I would strongly recommend running forced fsck to make sure all of
your filesystems are clean first; if the errors have been around for a
while, and for some reason the automatic fsck has been disabled so
they aren't getting checked, that could be really bad.
