next in thread | raw e-mail | index | archive | help
I had a machine running on 2.2.2 running under heavy load for 215 days. I
finally had to take it down to move it.
It's really really stable. :)
In case anyone is curious about memory leaks over a long period of time, I
dumped some outputs before I killed it.

Any reason why the number of interrupts received shows up signed? :)
I've got a 2.1 machine that's been up for 320 days now, before I kill that,
if there's anything anyone wants me to look at, let me know.
In any case, thanks to everyone who worked to make this system so stable. :)
