Hi, Currently implementing following scenario in ansible: Auto generation of configurations of Bacula backup system, in single playbook I generate both client and server configs (server configs generated by delegete\_to option to be on correct server) For small amount of hosts everything worked fine, but when adding many hosts to single playbook execution I face problem that bacula server is restarted too fast and fails at some moment with error: **failed because start of the service was attempted too often.** But actually I need to restart bacula server just once for all hosts. (single run per playbook, not per host) I did not find any solution for this, any recommendations/scenarios how we can achieve this? Of course as alternative I can run restart bacula server as separate playbook run but I think all in one approach is more correct. ---
