I'm not disputing the merits of NFS/TCP. I suggested this merely as
a workaround, and to see if the bug in question is causing the hangs.

Of course it would be better to fix the bug. But until someone fixes it...

There's no problem report on this. 

I can only speculate as to why the restart clears this up. The restart
shuts down existing NFS/TCP connections. This will force the client to
reconnect, causing it to recover.
