G'day all,

I've been getting some strange things happening with my samba setup. At
the moment we've got a SAMBA/LDAP setup to provide single sign/roaming
profiles for our Windows machines. We've got 1 PDC & 3 BDC's all running
Solaris 10 on Sun-Fire-V440's.

The problem is that the system seems to run fine for about a day or two
(users login/logout, etc), but then for no apparent reason users can't
log in.

If I run 'smbclient -L RAVEN' on the PDC, I get the following error:
session request to RAVEN failed (Call timed out: server did not respond
after 20000 milliseconds)
session request to *SMBSERVER failed (Call timed out: server did not
respond after 20000 milliseconds)

Having run the same command the night before, it all worked fine.

I can restart the SAMBA daemons (and the LDAP daemons), but nothing
seems to fix it. The only fix that seems to work is to reboot the
server. Once the system is rebooted, it all seems to work fine for a day
or two, then it just stops working again.

I've looked through the logs and can't seem to find anything that
indicates the problem. I've also searched the net for answers, but as of
yet, I've found no answer but to reboot the servers.

At the moment we're running samba 3.0.23b on Solaris 10.

Any suggestions about where to go from here would be greatly
appreciated.

Thanks in advance,
Shane
