I also got problems with my servers. They are crashing every 20-50 minutes. I am running AMXX 1.8.0 and MM-1.19p32 on DoD engine.
There is also a big DoD-Bug in the Clientversion where the Game crashes, but I am working on a bugfix. ;)
I hope that AMX-Bugfix will also come in next days
Edit:
Is there already a official statement from the AMXX-development-team?
