I've been semi-successfully running multi-homed ZFS based NFS file 
servers.  Every 30-90 days I have to reboot them, or they become 
non-responsive on one or more interfaces.  My only error messages are my 
RHEL 5 clients complaining the server is unreachable, and the output of 
netstat -i showing fast increasing input errors.  I am running 
10.1-RELEASE patched to 7/2/15.  Installed ports are minimal, mainly 
bash, rsync, portupgrade, and their dependencies.

Show daily graphics one of the servers on such parameters: 
1) pps on each physical network interface. 
2) The errors on each physical network interface 
3) IOPS on disk storage and the individual HDD (if you keep records) 
4) the total CPU load and each core individually. 

Also attach detailed information on the network card (for example, pciconf -lv em0, ifconfig em0), network and NFS configuration by rc.conf
