Well, I found the process that was causing the iowait but I couldn't find the
type of iowait it caused. We had plenty of disk I/O available, there wasn't
that much paging going on etc.

Anyway, with psio ( I could find the process that
was using the most I/O in the system. It was an Oracle process where one of
the data loads was a 10-line "insert into database1 as select lot of fields
from database2", so the communication between the two databases (both on the
same server) was too heavy to run.
