------- Comment From pa...@de.ibm.com 2018-08-30 08:06 EDT------- I've tried to reproduce the issue but failed miserably. I installed a fresh Ubuntu 18.04.1 made a cqow image essentially copying the filesystem for the guest. That means I was running the 4.15.0-29-generic kernel (reported as affected) both as host and guest. After an hour of running with 50 hogs (as root) I hit OOM but not the reported bug:
