We have a couple of Sun V880s running Solaris 8 and Trendmicro's "Internet
Web Security Suite." We are seeing some weird, load related issues on these
systems.

Notice that fork() fails - implies no memory. The size of the /tmp file
system is tiny, but swap -l and vmstat both report large amounts of free
swap space.
Any ideas of what might be going on? Lots of processes locking themselves
into physical RAM? Some other mystery?
