I'm still getting the same behaviour. linux 4.7.2-1-default I tried turning on echo 1 > /proc/sys/vm/overcommit_memory, and it didn't make a difference. I have plenty of memory KiB Mem : 16381576 total, 1104408 free, 8960096 used, 6317072 buff/cache KiB Swap: 2206716 total, 2120792 free, 85924 used. 6542176 avail Mem ps -ef says I only have 167 processes.
