External Call Problem fork/exec /bin/sh: cannot allocate memory

I get a lot of these errors with build 1814.
In terms of external program calls, I just use a couple of python scripts to control the Light Engine.

Memory usage gets up to 53% if I don't restart after each print, and I have to disable camera otherwise the Pi crashes mid print.

Any suggestions?

Try run commands below on SSH one by one, see if they make any difference.

sysctl -w vm.overcommit_memory=1
sysctl -w vm.swappiness=1

I used the supplied commands, enabled camera, and did a dry run.
Memory usage reached 55% and the file printed for 15 mins, then RPi crashed.

Please, attach a debug file.

Does it mean I have to do a fresh install?
