Issue

When using PING to backup Authentication Manager 8.2, receiving the following error:


CIFS VFS: Error -32 sending data on socket to server


The CIFS share is loaded with correct permissions; for example, a user can manually create files remotely. But when attempting to run PING to backup the user immediately gets the following errors:


CIFS VFS: Received no data, expecting 4


CIFS VFS: Error -32 sending data on socket to server

CauseThe problem appears to be caused by Opportunistic Locking being turned on.
ResolutionThe workaround is to disable Opportunistic Locking by running the following command in the PING shell:
echo 0 > /proc/fs/cifs/OplockEnabled

Note that this value will be overwritten each time PING is re-loaded. Adding it to backup/restore instructions or a script works well so that it is set correctly each time.
