[Samba] Samba 2.2.4 running in Tru64/v5.1

[William Wachob [EDCC / BannerIT]]

We are using Samba 2.2.4 (compiled from the web download) running on a Compaq ES-40 cluster (2-nodes) under tru64 v5.1.   Our problem is two-fold and any pointers on solving either of these would be greatly appreciated.   Shares disappear for no reason and no traces left in the logs.  This can happen once or twice a day.  Simply restarting Samba resolves the problem, but is embarrassing as the users often find it before the IT staff.  I am considering using modifying one of the "torture programs" to act as a "keep alive".  Any thoughts??   NMBD hangs in "Uninterruptible" state.  Originally when this was happening, we noticed that NMBD was also listening for UDP packets on the cluster "memory channel" interface.  I have since modified my smb.conf to look only at the appropriate tu0 interface of the system, but we still have NMBD processes that hang in the "U" state.  There is then a one to one correlation between these hung processes (they cannot be killed by anything other than re-booting the system) and process that appear to be waiting for UDP packets on ports 137 and 138.  Have we possibly missed something in setting up NMBD for the cluster environment?  Any suggestions on patches that could be made so that we could at least kill these processes with and unusual signal (perhaps a SIGUSR1 or SIGUSR2).  Again any help in resolving this problem would be greatly appreciated.
