One of our servers crashed and when we booted it again one Samba process
hung and grabbed one of the servers cpu's. When we killed the samba
process, another process generated 100% load on one cpu. From the log
file:
smbd/open.c:open_mode_check(555)
open_mode_check: exlusive oplock left by process 23227 after break ! For
file
profile/.../office.file.doc, dev = 900, inode = 2704003. Deleting it to
continue...
lib/util.c:smb_panic(1055)
PANIC: open_mode_check: Existant process 23227 left active oplock.
We tried to disable oplocks but no luck. After some more testing we
deleted all files in /var/opt/samba/lock (brlock.tdb connections.tdb
messages.tdb ntdrivers.tdb ntprinters.tdb share_info.tdb
unexpected.tdb browse.dat locking.tdb ntforms.tdb printing.tdb
) and restarted samba. This time it worked fine.
Is there som information about the tdb file and the inner structures of
Samba? What do we lose if we delete the diffrent tdb files?
We are using Samba 2.2.2
Regards,
Johannes
