Vacuum Crash

PostgreSQL 6.3.2 said:

NOTICE:  BlowawayRelationBuffers(places, 322): block 336 is referenced
(private 0, last 0, global 1)
FATAL 1:  VACUUM (vc_rpfheap): BlowawayRelationBuffers returned -2

And now I need to go find the vacuum lock file and blow it away, but I
don't really understand the above message, so wanna ask if I need to worry
about it...
