Description Clayton Coleman 2018-04-23 01:44:12 UTC

1. Start openshift-router
2. Hit CTRL+C

Actual:

Process does not exit

Expected:

Process exits

If I hit CTRL+C a second time the process exits.  It looks like someone double registered a sig trap handler somewhere in CLI or in the server code.

Marking high because this breaks process signal handling in at minimum the router.

Looks like it is a result of origin/pr/19063

I moved the handling of the signal closer to NewCommandStartNode() but that only works some of the time now (8/10 signal is delivered successfully). Investigating why that is because it was reliable before.
