Hi, In our project, the taskflow is used to back up and restore data. After the task is submitted or started to run, the task may be suspended. However, the program process still exists. It seems that the thread for executing the task is missing. After the program process is restarted, the task can be resumed. Can you give us some advice. Thank you. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-discuss/attachments/20220210/af3316e7/attachment-0001.htm>
