This is not pure polygraph question, but I need your experience to help me
I'm installing FreeBSD 3.4 on Dell OptiPlex GX110 desktop machines. All
setup procedure is good but one problem - the system doesn't recognize more
then 65MB of RAM!
BIOS and NT OK with the 256MB./ FreeBSD is not.
I have installed the system on different hardware (IBM, Gateway) and they
recognize the real memory amount (128MB and 256MB).
Can anyone help me with this?

You are probably running out of memory on Polygraph machines.
When proxies cannot respond fast enough, PolyMix-2 robots will queue
waiting transactions and that consumes memory. You may want to search
for "virtual memory exceeded in new" postings on this list.
As a rule of thumb, you must ensure that polyclt/srv processes
do not page. Another important thing is to monitor memory allocated for
kernel network buffers. If that memory is exhausted a machine can become
unusable (try "netstat -m" on FreeBSD).
