Fortunately, you've hit an actually fixable problem that you may not need a reboot - you just have a lot of processes waiting for a remote NFS file system to respond. Go find out where the mount is from, and why it's not responding. Fixing that will likely clean up your issue.
If it is indeed coming from nfs mount, check if it is mounted in synchronous mode, and try to switch to async. See if it made any differences Regards, Mulyadi -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
