# It can also happen that the kernel oom killer interferes and kills important tasks.
# A reasonable value to avoid these issues appears to be 75% of available cores.
# LITFLAGS is an env vars that can be used to achieve this. It should be set on command line or in files read by your shell on login (like .bashrc ) .
# example for systems with 24 cores

# NOTE: It's your responbility to validate the value of LITFLAGS. If unsure, don't set it.
