and to make it somewhat easier to login :) start just a few servers at boot, then start one at a time until you see problems. Then it's time to stop that last one, and either increase memory or move the not started servers into one or more other Linux machines.

Hmmm - high "sys" CPU usage, high loadavg, system not talking to anyone. Smells like it's busy doing its own stuff. If it were me I'd want to know trends for things like swap-in and swap-out rates, tasks in uninterruptible sleep, context switch counts. SAR is too granular to be any use even if it did have the data. Set up a background script to run top and vmstat and write to disk every so often. A quick bit of awk should show the trend. You could do all the probing of /proc yourself, but I find it easier to allow things like top/ps/vmstat do all the grunt work.
