We've had similar troubles with Samba 3.x on our ClearCase VOB server

to tracking down the problem fully.  I had hoped that upgrading to RHEL4
using a 2.6 kernel would help, but your experience doesn't bode well for

We had similar problems. stracing hung child smbd processes pointed the
finger at *local* locking issues: processes were hanging in
fcntl(...,F_SETLKW64,...) for one byte locks on fd 14 = locking.tdb; the
culprit function is tdb_brlock.

What is the local filesystem?  And remind me what server OS this.
RHEL 4 ?  Thanks.

Same problem on both ext3 and xfs. This is running on Mandrake 10.2 (Mandriva Linux 2005 LE), with a 2.6.13 kernel.

Since turning off oplocks things have become *much* more stable, if rather slow.
