What finally fixed the problem for us was to turn off Receive Side Scaling 
(RSS) and TCP Offloading on the network adapter as outlined in Knowledgebase 
article esg101078.

Subject: [Networker] 7.6.1 - Savesets hang

Hi,

I have the same issue.

NW server on win2008 R2 64bit 7.6 SP1 build 466

clinet - win2008 R2 64bit 7.6 SP1 build 466

backup is about 4T to AFTD. The backup hangs after 300G sometimes 60G and 
sometimes 200G.

Have raised sev 1 ticket with EMC, got their engineering team to look at it but 
they still can't figure out what is the issue.

Have disabled  TCP autotuning and have made registry changes but no luck
