Hi Ethan, I assume this is from an AIX box (right?)
Some remarks: (not an answer!) The first line of vmstat/iostat output is an average since restart. The 'wa' is 32 and you have 4 processes blocked on average. Was there a problem (or a large load) since your last restart that was since solved? If not, this may just be the average load... On the other hand, you aren't currently paging in/out nor have an abnormal amount of context switches (cs) or system calls (sy), so why should two processes be "blocked for resources I/O, paging, and so forth" (as per man page). Worth investigating! Unfortunately, *NIX does not provide the equivalent of V$ views so we really cannot dig into the details.
