do you know what the IO is? is it swapping? are you running collectl
or similar so you can look at historic performance data?
G
It's not swap, and happens regardless of the amount of the ram in the
server.
I've run "sysctl -x 1" for random periods of time both before and after
the issue hits and the IO is very low, < 20% most of the time with is
typically < 5% usage.
But when the problem happens sysctl reports > 95% usage.
