Good day.
I have a Sun Fire V490 (8 CPU/16GB Mem) server running Sol 10 6/06 and
am seeing some concering metrics when running mpstat, especially major
faults. The server acts mostly as an NFS server as well as a samba
server for user home and data directories.
Any thoughts on how to proceed or references appreciated.
Thanks,
Peter
