I'm not sure why your server is experiencing higher load when you install blocklists. Are you sure all the blocklists you've chosen are working properly and replying in a reasonable timeframe? Have you tried manually testing the blocklists to see if they're putting a load on your server?
The SMTP message from active monitor includes stuff about the CPU being abnormally high as a "possible cause", but this doesn't mean that is why your SMTP shut down (or appeared to shut down). This is just one of the possible causes.
In my experience with blocklists, I get this message from the active monitor every once in a while (once every few weeks) even though the CPU load is around 0.5.
