NSS pool errors during every NSS background check

Question

We are running a NW 6.5 SP6 server with NSS pools SYS and POOL1.
POOL1 contains two volumes: VOL1 and MAIL. Both can grow to max. pool size.
During every NSSbackground check we receive the messages below.
I checked the novell support site, but can't find anything usefull on this.
Anyone got an idea what they mean and how to get rit of them?
Kind regards,

This one zeems to be
"20012 zERR_MEDIA_CORRUPTED: The media is corrupted."
This may indicate that it is time to do a pool rebuild, although I don't know enough about what line 510 of beastTree.c is looking for to say much about what the actual problem is.
