# Increase the soft and hard RLIMIT_NOFILE and RLIMIT_NPROC limits.
# By default they are 256/unlimited and 709/1064
# and they sometimes create problems to the build process and telegraf.

# NOTE: If the limits are not increased enough, it might be because of
# restrictions set by the kernel. They can be temporarily altered with:

# sudo sysctl -w kern.maxproc=xxxx
# sudo sysctl -w kern.maxprocperuid=xxx
