So I have a new server that is up and running with Centos 6, and the load average is stuck hovering around 1, even when the machine is nearly idle. I reviewed the process table and found this running:
root@myserver:~]# ps -efl|grep " [D] "
1 D root 43252 2 0 80 0 - 0 rpc_wa Apr01 ? 00:00:00 [10.125.50.56-ma]
The timing (Apr01) lines up perfectly with my trending graphs, and it was right around the time I was working with mounting an NFS share from that IP address. However, the thread is in uninterruptible sleep, and I don't know how to get rid of it. I have unmounted any/all NFS mounts I had, and it still won't go away.
Does anyone know what this process/thread is, and if there is a way to help it exit without restarting the box? It is already in production so I'd really like to avoid that.
