[Glass] FindFreeFrame: potential infinite loop

[Dale Henrichs]

Pieter,

This message indicates that you've filled up your SPC. The likely situation
is that you've got one or more gems in the process of doing "large commits"
that are hogging most of the pages in the SPC. Gems are allowed to preempt
most pages from the cache, but pages that are involved in a commit cannot
be pre-empted and _could_ lead this situation....

If you are not running statmon, you should. Statmonitor has a number of
stats that make it possible to view the health of the SPC and we can pretty
much tell what's wrong by looking at the statmon output.

Dale
