NFS hangs require reboot

[yousif282]

i have a problem with nfs the it suddenly hanged and i could do anything about it even restart the service didn't work , so i update my system to 11.2 U2 and it worked fine until this morning where it happened again and only restarting the server made it work
is this a bug or something else ?
any help would be appreciated

Anything in /var/log/messages around the time of the hang?
What are the hardware specs?
How many connections to the share?
