SLES12SP4 and upper version
We recently encountered a SLES12SP4, or SLES15SP1 system crash (soft lockup...) when running our applications. After some trial and error, we found that we have to disable numa_balancing in kernel settings to resolve the problem. NUMA balancing is good feature in OS that is to boost the normal application performance by ~20%, however, due to the "bug", we can not enable it.
Does anybody have the same problem? I am wondering if it is a SLES OS bug that SUSE has already known and has a fix on it.
