bad inode number:0 ??

I have gotten this everytime I have heavy disk activity (such as queueing
250 incoming mail messages and then running mailq which then runs procmail
for each message and for most messages filters it to a script which posts it
to the news server I run on my local machine:

<datestamp> lighthouse kernel: EXT2-fs error (device 09:00): ext2_read_inode:
bad inode number: 0

It happens once and since I have the 'errors=remount-ro' option set, it tends
to remount root readonly (yes, md0 is root on my machine) I remount rw
and don't get anymore errors. What could this error mean, anyway? Is it
in any way related to using md0 as a root filesystem?

Thanks for any suggestions,
