I'm not sure if this is the correct forum for this kind of question
but here goes anyway.

We have a Sun 4/280 running Sun OS3.2-4 and have had very few problems
with it. Today for the second time since we received the machine I noticed
that almost all the processes were being swapped! I can't seem to find 
what is causing this erratic behaviour.

The output from vmstat shows that there is at least one process that is
I/O blocked. Here is the output from vmstat:

It looks like the system interrupt level is pretty high and at the moment there
are only 4 people using the machine. The last time this happened I had to 
reboot the machine to bring it back to normal. Today I'm going to wait for
a while to see what happens.

By the way how many of you have received Sun OS4.0? I would have thought we
would have seen it by now! Does it really improve system performance like
some of the rumors say?

Thanks,

dan
