the last time it hung, it hit about 45 ... about 6 hours ago, it was at
~5-10 ... anything I should look at to figure out where those 39+ are
'busy'?
'b' stands for "blocked", not "busy". Judging by your page fault rate and
the high number of frees and pages being scanned, you're probably swapping
tasks in and out and are waiting on disk. Take a look at "vmstat -s", and
consider adding more RAM if this is correct...
'k, I will keep an eye on things and check vmstat -s as those numbers grow
higher ... thanks for hte clarification on 'blocked' vs 'busy' :(
What specifically should I be looking at in vmstat -s? note that the
server just rebooted, 0 swap is used:
# pstat -s
Device 1K-blocks Used Avail Capacity
/dev/da0s1b 8388608 0 8388608 0%
and vmstat -s is showing:
