concurrent map panic #188

Closed purpleidea closed 6 years ago

purpleidea commented 6 years ago

I don't know what caused this one, but it happened with git master. Should be easy to follow if you know the code base. (Sorry I would normally write a patch, but I didn't dig into the code yet since I'm overcommitted with https://github.com/purpleidea/mgmt/ )
