The kernel version that you are using supports cgroups -
https://www.suse.com/releasenotes/s390x/SUSE-SLES/11-SP1/#ResourceManagement
and
has it enabled by default (if the memory cgroups feature is not needed, it
can be switched off by passing cgroup_disable=memory on the kernel command
line, reducing memory consumption of the kernel a bit.)

Perhaps a memory cgroup could help in this situation?
