Occasionally unable to mount shares.
First found: Starting up switch with 8 devices connected, only 6 was able to connect to the share. If a remount is ordered the devices are able to mount the share.

Using Debian Jessie mount.cifs to mount the shares.
attaching log file for a test session with 8 threads which ended as soon as the first mount attempt failed.
