The 'b' column of vmstat shows pending transactions that require disk I/O. 
Does that include NFS connections?

Have a machine with very high numbers in that column, yet when I do top and 
select 'm' to show disk activity, the numbers in top are fairly small.

Wondering if the issue is the communication with the NFS servers.
