      Description

      This warning looks like an error. Why do you need the max processes so high?

      I cannot set the maxproc on OS X above 1024.

      sudo launchctl limit maxproc 1024

      If, I increase, it asserts:

      ulimit -u 1025
      ulimit: max user processes: cannot modify limit: Operation not permitted

      But this works:

      ulimit -u 1024

      The startup warning is:

          "startupWarnings": {
              "log": [
                  "Wed Jun 27 19:02:40 [initandlisten] ",
                  "Wed Jun 27 19:02:40 [initandlisten] ** NOTE: This is a development version (2.1.2) of MongoDB.",
                  "Wed Jun 27 19:02:40 [initandlisten] **       Not recommended for production.",
                  "Wed Jun 27 19:02:40 [initandlisten] ",
                  "Wed Jun 27 19:02:40 [initandlisten] ** WARNING: soft rlimits too low. rlimits set to 1024 processes, 20000 files. Number of processes should be at least 0.5 times number of files.",
                  "Wed Jun 27 19:02:40 [initandlisten] "
              ],
              "ok": 1
          },

      I added this in /etc/sysctl.conf and rebooted but nada:

      kern.maxprocs=2048
