If I don't see 100% usage on all cores, I'm not doing my job.

ganglia script + nvidia smi helps the higher ups rationalize...

It's over 30k connections to web server with nginx-apache chain. Most of processes is apache2 forks, second mysql unable to process too many queries, and apache wait response from it, but nginx send to apache more and more connections, and doesn't receive responces from apache, who wait responces from mysql.
It's one of kind DOS, fork processes to script which have heavy mysql query. I have consistently turnf of mysql then apache, after start script to drop more than 100 same connections to 80 port

Sounds about time to get at least a separate database server. Running on a shared server you'll never be able to give it sufficient ram to efficiently handle the workload.

104.7 when i fired off a self-replicating script to convert about 2.000.000 day/month/year hour:minutes:seconds lines across roughly 100 files

Best I've gotten is about 700 on an overloaded mail server whose disks couldn't keep up.
But sweet, fancy cheezus, what did you do to that poor machine for 16000?!

You're doing it wrong. Nice to see they fixed the behavior of the load average wrapping back to 0 from 1024, though. If not for that, I suspect my record from intentional forkbomb tests would be way higher.

I had a server spike to about 8k for several months once. It was because of a stale NFS mount. It was totally responsive, just had a bigass run queue.

FML. That's us right there. Stupid Ubuntu background processes on LTSP servers doing trash collection/monitoring on network filesystems because they removed the NFS exclusion in U9.10.

Unrelated: isn't Monaco just the sexiest god damn font ever?

I don't know, couldn't get top to run after the fork bomb went off.
BTW, I hope that potential DDOS on web00 isn't serious.
