I have had a problem in the last few days where every 10-15 minutes, my entire server goes non-responsive, shutting out all TCP connections, for about 3 minutes.
I finally found that the connections shut out because all 16 cores spike to a solid, stable 100% CPU for the duration of those 3 minutes.
I am actively trying to find out what is maxing out the CPU, however, as everything on the server totally freezes (even in the console), I can't check fast enough to find out what it is.
This is obviously a big problem and I need to get it handled right away. Is there some way to log this CPU spike and distinguish it from the rest of the traffic?
