Totally agree. It can really shit the bed hard it can. I had an 0.8 cluster that crashed with a never ending leadership election. Only option was to burn the whole cluster to the ground and reinitialise it from scratch. That issue seems to have gone away since 1.0 but I’m not sure I can sleep after running it for a couple of years. Every time I bounce a cluster node for patching I clench.

I could write a book on the problems I’ve had with vagrant as well. Lost at least a day a week to that in the last month.
