Celerra Interconnect question

SAN Admins,

I have CIFS replication setup for 3 shares. When am copying any data almost 2 Gig, the interconnect fails and recovers after 5 mins and the file transfer stops. Whereas when am copying any files upto 300 MB into the share, the copy happens fine.

To be noted, this happens on all the shares but not limited to one. The link speed is 1 Gig.

Output from the server_log server_2:

Am I missing any data mover parameters for this disconnect ?

Any help is much appreciated !
