Here is a list of the relevant MFCs 194358,230394,230441,230489,230552,232116,232420 and r227059 This code has now been in 7-STABLE for two weeks . >How-To-Repeat: Running multiple 7.4-RELEASE servers that uses NFS mount directories there exists two nasty issue. If client a reads a file o r directory as client b changes the file or directory , in a short enough amount of time, client a never sees the file or directory changed and it will see old data and attributes for this object until it attempts to write to it . Secondly when multiple NFS client using lockd, are under a moderate work load the client will crash due to a rpc bug brought about by high rates of locking. >Fix: The following MFCs need to be merged into the 7.4-RELEASE branch.
