Description

Looks like cgroup_fj_stress_memory_* tests fails on ppc64le. The trace from:

https://openqa.suse.de/tests/3766528#step/cgroup_fj_stress_memory_10_3_each/6

seems to suggest that the system got OOM in the middle of forking new processes, we are forking ~1000 processes there on a machine with 1GB ram, which means that we have less than 1MB per process, which may not be enough because ppc64le has 64k pages, which makes each new process more memory hungry.
