Ever since upgrading our Netware 6.5 server to SP4, I have noticed that
the Total Cache buffers continue to decrease on a daily basis. 6 days ago
the server was rebooted and had 400,000 Total Cache Buffers. Now we are
here, 6 days later and the Total Cache Buffers are down to 70,000.

How can I trouble shoot this to determine what is sucking up all of the
cache buffers and not giving them back?

The server is running an arcserve agent for netware to backup to another
server and ZFS 6.5 subscriber service.
