Your I/O is quite high, lets start by running the following:
Let us know the output of each command.

Please find the screenshot attached, let me know if you need further..
thanks!!

Are you still having the services failing and slowness from your first post? I could see this happening for a bit, as ndo2db did not seem to be started and surely has to process some performance data now.

Still having the same problem. I hereby attaching the output of top for your reference.
