I've run into issues like this before with a few clients and it has always been 
either keep alive settings or the group's inactivity timeout.

I agree that the keep alive time setting should be added. Try that and restart. 
I can't remember if a reboot is required for the os settings to take effect.
Hope it works for you.

Check logs on the client for hardware issues (dmesg, /var/log/messages, 
/nsr/logs/*). Then, if all seems well, run a tar on the file system in question 
and make sure it is able to walk the entire file system.

tar cvf - / | cat > /dev/null

Another issue might be a firewall between the client and server with a 
connection table time out too short for your session. The solution is to 
increase the timeout (if possible) or enable TCP keep alive on your server. 
This is my setup:

# more /etc/rc2.d/S93nettwicks
#!/bin/sh

# Helps to solve RPC errors under heavy load.

/usr/sbin/ndd -set /dev/tcp tcp_conn_req_max_q 1024 /usr/sbin/ndd -set /dev/tcp 
tcp_conn_req_max_q0 4096

# Should help with backups thru firewall

/usr/sbin/ndd -set /dev/tcp tcp_keepalive_interval 600000
