We have a network of five Macs. I used HeapFixer
to set the system heaps on all of them.  I set
them above recommended amounts to make crashes
unlikely.

Today, two of them crashed. When I checked the
heaps, they were set to 80k larger than normal,
which is how they usually are before resetting.

A third machine, which had not crashed, was also
set to 80k, though I had set it to 512k larger
than normal only a few weeks ago when I installed
a hard disk and new system.

Two of the Macs are SEs and one is a IIci. My II
and an SE had their heaps set to large values.

The question is: what could cause the system
heaps to be reset? I haven't installed new
systems on these machines since resetting their
heaps. What other action on a user's part could
cause the heaps to be reset?

I'm mystified.
