printer tdb file corruption

[Kristaps Rāts]

Hello,
we have a samba 3.0.14a host as a print server and today it went awol -
an smbd process is eating up 99% cpu time and printing doesn't work.
After restarting samba everything looks normal, but when someone tries
to print the same thing happens again. On startup the logs go something
like this:

[2006/04/23 15:18:55, 0] tdb/tdbutil.c:tdb_log(725)
  tdb(/var/cache/samba/printing/HPLJ1200PS.tdb): remove_from_freelist:
not on list at off=107956
[2006/04/23 15:18:55, 0] tdb/tdbutil.c:tdb_log(725)
  tdb(/var/cache/samba/printing/HPLJ1200PS.tdb): tdb_free: right free

After removal of the offending tdb everything went back to normal -
samba created a new tdb (about 5 times smaller than the original) and
printing works again. Anyone care to look at that pesky tdb?
