Public bug reported:
System freeze occurs when memory is almost full and there is no chance
to kill processes. Everything is unresponsive, hdd is trashing, even ssh
connection does not show any reaction. I set vm.swappiness = 1 to
minimize swapping but those lock ups are still there. I think this could
be related to disk caching. Few times I observed in iotop that several
processes use %90+ disk I/O while memory is close to its limit. I
increased vm.min_free_kbytes (default value was 65536) but not tested
yet. Current disk scheduler is set to deadline.
