Hello,

        We have a Re2. We use this machine to generate all the visual
environment, aircraft math model calculations and received control input from
the cockpit. We also use a TCP/IP connection to send flight data to a PC and
received HUD info. from the PC.

        We have a problem after we start the TCP/IP connection. The simulator
will have core dumped after running for a while. We track the error through dbx
and it shows the following message :

        dbx version 6.2 Mar 9 1996 15:23:28

   6 __istart() ["crt1tinit.s":13, 0x412860]

This message is for all the core dumped. Do you have any idea why it always
happens in pfFrame? What is the solution? I will appreciate for your help.
