I'm getting the message "Server logical address space is running low. Increase the available logical space by restarting the server with the -u390410240" on my BorderManger server. I already have the -u 512000000 for Surf Control and I don't think I should put anymore switches in there. Is there a way workaround this issue?

Also, my BorderManager server just dropped communications today, I could not ping it and other servers lost connection with it. What log file would hint as to what happened.
Thanks.
