Having an issue with CIFS mounts that are defined to the SLES 11 SP4 server that cause the ability to interact with it to become extremely slow in responsiveness when the mount becomes unavailable. In this configuration, the mount AA_NexPress_1 is associated with a folder on Windows Server. If for example the Windows Server were powered down RDP session with the SLES server are pretty much locked up. I can ssh into the SLES server and go to any directory and do a simple ll list except root where these mounts are defined. As soon the NexPress Windows Server is up and the directory is reachable the SLES server immediately starts responding normally.

Below is the directory definitions for the mounts, as well as the mount definitions in fstab.

drwxr-xr-x 2 root root 0 Jun 2 11:10 AA_NexPress_1
drwxr-xr-x 2 root root 0 Jun 24 13:57 AA_NexPress_2

// /AA_NexPress_1 cifs auto,domain=ebnt-1,username=dbcuser,password=xxxxxx 0 0
// /AA_NexPress_2 cifs auto,domain=ebnt-1,username=dbcuser,password=xxxxxx 0 0

Is there a parameter I can set with fstab so that it times out if the mount becomes unavailable?
