[Samba] Locking DB corruption

[Ross McInnes]

This is the second time this has happened this week, im runing Samba 3.05
fairly standard config.

It happened on Tuesday, when there was no one about (2 maybe 3 users) we
were rebuilding a few machines and everything was going fine. 

Any machines that were logged on would work fine, but new machines failed to
log on.

We run a small perl script every 15 and 30 mins which run smbstatus to find
out who is logged on where, and then works out their quota to see if they
are close to running out of space. If they are we use smbclient to send that
machine a message.

This is the result of that perl script when it finds the locking.tdb is
corrupt.

Any thoughts/ideas as to what this could be?

Many thanks
