Angelox, one more thing regarding the memory usage and your database - I just looked (curious) as I have been running your complete DB since your Harbinger updates. 7 of my 10 dynamic zones are running at 600k RAM or so. Only 3 are above 6mb, and none are over 100mb (I would have noticed that, actually).
So I am not sure why mine is different. I do have crashing zone issues, but that's caused by my crazily over-twinked monk friend trying to tear down my server daily.
Edit: Uh, nevermind this retarded post. I am a Windows user, not Linux. That's sorta different, eh?
