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?
