I am having similar issues, the mod put too much load on the server, i am 2x DualCore Xeon 2.8 with 2GB ram 100mbit.... Cron set to run every 24hrs or midnight

... once the cron run the load shoots up to 6 - 20 till apache crashes....
even now the server is dead slow due the gateway.php cron
Code:
xyz 18394 11.2 3.6 86660 74972 ? Ss 00:00 25:39 /usr/bin/php /home/xyz/public_html/forum/gateway.php
i have also noticed, sometimes gateway file (but stop leeching from news server) never get killed automatically, on next cron another process is created...
This is a great hack, but someone need to update and optimize the code.
