Issue

When trying to mount a FlexCache Volume or Qtree junction-path, the server hangs and the mount is unsuccessful. 
Listing or traversing the FlexCache volume after mounting its parent path has the same behavior.     

The following logs can be seen in EMS: 

Wed Dec 30 14:08:33 +0200 [Node01: nblade2: ems.engine.suppressed:debug]: Event 'Nblade.JunctionRootLookup2' suppressed 18211 times in last 121 seconds.
Wed Dec 30 14:08:33 +0200 [Node-01: nblade2: Nblade.JunctionRootLookup2:error]: Junction root lookup of a volume in Vserver 100 with MSID 12345678 has failed for reason "SPINNP(3010)".

and 

Wed Dec 30 14:06:48 +0200 [mtrlabfs-01: kernel: Nblade.dBladeNoResponse.NFS:error]: File operation timed out because there was no response from the data-serving node.
