Let me know if I can help, I'm in the right time zone :)

FWIW we've been running with oplocks off since September
2001. [Mail archive 13-14th September 2001, ianjhart and
"ict technician"]. This is a live system from 8am 'till
9pm so I've not had chance to fix it. We've a holiday
coming up in February if this is still not resolved.

I can run up a test box at work on Monday. My email
address there is ict at
We only got problems under high load (many logins), if
you can see an error under no load I can run up a windows
box at home and help you test.
