Hello Tang, Openstack slaves only have a single executor so what you are probably seeing is due to using build slaves that have multiple executors. There were a few bugs[1] that was fixed recently around these types of deadlock issues. The new gearman-plugin release[2] contains fixes for those issues. Also if you want to test the gearman-plugin with Jenkins independently of zuul you can use the simple gearman-plugin-client[3] to send jobs your gearman server to see if the jobs get built.
