Hi Team,

We recently upgraded to Jenkins 2.277.2 as part of that, we upgraded openstack plugin to 2.58.

After upgrade we are experiencing some issues. The openstack slave instances which are launched via plugin & marked with retention time as -1 ( to lock in "keep it forever" mode) got terminated.

openstack slaves got removed from jenkins and Jobs which are using that openstack slaves were aborted in middle run.

In the backend as we checked in openstack dashboard the instances were terminated.

Please find the jenkins logs were our locked slave instances centos7-2698 & centos7-2699 are terminated while being used by jobs, because of periodic slave cleanup.

Jenkins logs:
