What's the number of times the letter "4" appears in:
Q: Processes during stress test get killed I've run into a somewhat curious situation.
I'm currently stress testing a couple of new machines running Fedora 20. I've tried mprime, memtester and systester.
All execute for a while and suddenly end with nothing besides a "Killed" message. Nothing in the kernel about it needing to kill processes or anything else relating to it. The tools themselves also do not report any errors.
I have custom limits set for users, but the processes in question are run by root, so it should not be interfering.
SELinux is disabled.

A: Error was on my part, I changed the limits and didn't restart the sessions running the jobs, so the old limits were still in place.
