>Description:
         There are multiple NFS client bugs that need to be fixed in the FreeBSD 7.4-RELEASE code base that have been fixed in 8-STABLE, 8.3-RELEASE 9-STABLE and HEAD. 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.  MFCs 194358,230394,230441,230489,230552,232116,232420 and r22
