SYMPTOMS

It may take approximately 35 seconds to delete files over the network. This problem occurs approximately 10 to 15 percent of the time. A network trace of the problem shows the following frames:

Client -> Server - C NT Create & X, File : \test.txt - request for OpLock\OpBatch
Client -> Server - C Delete File, File = : \test.txt
Server -> Client - R NT Create &X, FID = 0x8003 - oplock level = Batch
Server -> Client - C Lock - Break Oplock

A delay of approximately 35 seconds occurs at this time.

Server -> Client - R Delete Status_Sharing_Violation
Client -> Server - C Lock & X, FID = 0x8003 - Break OpLock
Client -> Server - C Delete File, File = : \test.txt
Server -> Client - R Delete

The first two frames are from the client. The initial frame is an "NT Create" message with a request for Oplock/OpBatch for the file. This is followed by the "Delete" request for the same file. The next frame is the server's response to the "NT Create" request with a Oplock level of "batch." The server then sends a Break OpLock message for the previous frame so that it can delete the file. The server then waits 35 seconds (until its OpLockBreakWait time-out value has expired) before the deletion does not work. The client can then release the lock and try the deletion again.

CAUSE

When the Break Oplock request is received by the client, the client cannot process the request because it is already waiting on the Delete request. The server cannot handle the Delete request until the Oplock on the file has been released. This causes a pseudo-deadlock condition that is broken after the server's OpLockBreakWait time-out value expires.
