Thanks for picking up the investigation. Does that mean that the above fix was partial and that there likely is a use after free somewhere else? It's good at least that this ZMQ_ROUTER_MANDATORY option catches that. (Also, these scary Btrfs errors are a reminder that the file system got corrupted at some point and should be recreated at some point -- I hope they are not related to the problem at hand but we should keep an eye on things). --=20 Thanks, Maxim
