This one shows that served does not allow client reconnection because  
it is still
busy processing other requests from this client. That's the reason for  
"mount hang".

This is all I can tell from those logs you provided. If the logs  
actually span
long in the past, might be there is more useful info.
Since there was disconnection - perhaps dmesg on client and server  
contain
more info about the disconnection reasons, also on server if you do
sysrq-t, you will see what is going on with those server threads that  
are supposedly
still process client requests.
