OK. I am not familiar with any of them. Are they related to java? Have never 
worked on java myself.

I was talking about OOM killer behaviour, which was beaten to death for last

I agree. but with the input provided, I think that remains as viable option.

Well, I agree they are different but not that much..:-) And  besides man tuning

that was just one example why freeBSD is better server OS, out of the box, 
compared to linux.

No flame wars.. Peace..
