I have a Solaris 2.8 sunfire v120 server with 2GB RAM.
When I run vmstat I am getting a large number of continually swapped out
processes (45 and above). The box is busy with a lot of I/O (mainly to
mySQL).
I had an issue connecting to the box this morning (although this may be
a red herring). The vmstat output shows ....

The paging out isn't continuous, I get a burst now and again.
The summary of prstat details ...
NPROC USERNAME SIZE RSS MEMORY TIME CPU
1 mysql 38M 9032K 0.9% 0:00.23 37%
97 root 1381M 692M 70% 0:20.45 12%
15 nobody 68M 27M 2.8% 0:11.29 0.0%
1 daemon 2528K 1160K 0.1% 0:00.00 0.0%
Total: 114 processes, 553 lwps, load averages: 28.54, 29.31, 25.83
What is troubling me is the 45 processes that have been swapped out
waiting for I/O.
How do I see which processes these are, are they a problem and how do I
clear them down.
Thanks
Regards
Andy
