It's a strange situation.

The checkpoint is a 4.1 sp1 on NT 4.0 sp6a with 4 nics on a compaq proliant
server. Everything seems to work fine. No errors in event or system log
on NT. Checkpoint logs are okay. everything works okay but periodically
the vpn stops working. The only error that shows when this occurs is a
system log entry that says a memory address could not be read. Their is
plenty of memory assigned to the checkpoint kernal. system memory if fine
( system has 512meg of ram). System works fine, after starting and
stopping the firewall service, for a while but eventually the error occurs
again. running memory diags on the server show no errors. I can send more
details if needed. let me know if anyone has seen this problem before. No
mention of it in Checkpoints support docs.

Thanks.
