   * *NOTE* There is currently a bug with PM2 when in cluster mode. The
   * issue is that PM2 is receiving the config/env variables
   * (i.e out/error log location, add date to logs, etc.), but it is
   * not using them. The logs are going to pm2.log and there is no
   * date added to the start of each log line.
   * Once this bug is fixed the exec_mode can be switched back to
   * cluster and this change can be reverted.
   * The version of PM2 that this issue is happening on is 4.5.6**
