Apache high load due to NFS timeouts nfs_wait_schedule /proc/sys/kernel/hung_task_timeout_secs

nfs client : nfs: server not responding, still trying, Apache sudden high load freezing the box

Solution
1. increase the nfsd servers start number
2. switch to UDP : settings for the fstab line:
nfs noatime,rw,rsize=32768,wsize=32768,udp,nolock,hard,intr,async,nodev,nosuid 0 0
3. force the ethernet device driver AT both sides NFSD server AND client Duplex to full
/usr/sbin/ethtool -s eth1 speed 100 duplex full autoneg off

cheers
