I am running a heat list command, it fails intermittently and works other time. It seems like rabbit mq having some issue on receiving the message from the heat-api. But anyone facing issues like these and suggestion would be appreciated.

This is usually because there is too much load for heat-engine to respond before the timeout. The load could be actually caused by heat-engine, or anything else on that host, so it is hard to say specifically what your problem is.

HEAT-LIst hangs, when I created 70+ stacks with. I hope it has scalable issue. Even nova says no quota exists, still heat create the stack, this creates issue. When I cleaned HEAT DB down to 20 stack, becomes normal. Any thoughts on this?
