   I am unable to reproduce this on OS X, SmartOS or Ubuntu. With the latest master build, I ran the following and 100/100 tests run on all three tested environments:

   time (OK=0; NOK=0; for i in `seq 100`; do ./node test/parallel/test-child-process-fork-net2.js && OK=$(($OK+1)) || NOK=$(($NOK+1)); echo "$i   OK: $OK   NOT OK: $NOK"; done)
   

   Also, what about a smartos label for this?

   Also, let me know if I messed up the reproduction recipe.

   FWIW, I haven't been able to reproduce this locally on OSX and Linux either.

   Good to hear. :) I'll keep moving down the list and updating with either a PR or a similar update to this one.

    Thanks. FYI, we are coming up with a Jenkins job to stress individual tests in CI, so we can quickly verify if a test is really flaky or not.

    Cool. I've got scripts on *nix and Windows to run similar tests like above. If I can help, let me know.

    Given that the flakiness has not been reproduced, I'm going to close this. Anyone should feel absolutely free to re-open with no hesitation at all if you think I'm being rash or if the issue does re-appear.

    Sounds good. Verified NOT flaky in CI: https://ci.nodejs.org/job/node-stress-single-test/4/nodes=smartos14-64/console
