Thank you Paul for your response. Perhaps I can give a bit more info: RS/6000 H50 w/AIX 4.3.2 running Samba 2.0.5a PIII-450 NT4sp4 w/128MB I indicated yesterday that a race condition appeared to be happening. I later remembered that I turned on level2 oplocks on two read only shares as the last tunings we did before this began to happen. I got the info from the Speed.txt document in hopes of increasing performance on our read only shares. After turning this feature off, it appears the problem has gone away. It should be noted that we were writing to one of the shares froma client with level2 oplocks turned on. It was necessary to copy a section of the drive to somewhere else. Could this have upset some delicate balance? Thanks! Bill -- /------------------------------------------------------\ | | | William E.

This is why I'm glad Andrew persuaded me to have the feature default to "off" in 2.0.5a :-). I have a fix which will be in 2.0.6, please ask if you need me to dig out the code changes for 2.0.5a.

They are off by default because they haven't received enough testing yet, as is evidenced by the bugs that we've found recently. Cheers, Tridge
