Reproducing the problem to get the above outputs gave me better understading on conditions that lead to this problem.
If there is high load on virtualisation hosts when vms containing Rabbit server get rebooted the timeout is likely to happen. If reboots happen when virtualisation hosts have low load Rabbit starts without problems. Maybe vm is too slow during startup for Rabbit to be ready before Systemd times it out. If that is the case maybe this is not Rabbit bug after all? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1783325 Title: Rabbitmq-server times out during server startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/1783325/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
