When Neutron is killed with SIGTERM (like via systemctl), when using ML2/OVN neutron workers do not exit and instead are eventually killed with SIGKILL when the graceful timeout is reached (often around 1 minute). This is happening due to the signal handlers for SIGTERM. There are multiple issues. 1) oslo_service, ml2/ovn mech_driver, and ml2/ovo_rpc.py all call signal.signal(signal.SIGTERM, ...) overwriting each others signal handlers. 2) SIGTERM is handled in the main thread, and running blocking code there causes AssertionErrors in eventlet which also prevents the process from exiting. 3) The ml2/ovn cleanup code doesn't cause the process to end, so it interrupts the killing of the process. oslo_service has a singleton SignalHandler class that solves all of these issues Closes-Bug: #2056366 Depends-On: https://review.opendev.org/c/openstack/oslo.service/+/913512 Change-Id: I730a12746bceaa744c658854e38439420efc4629 Signed-off-by: Terry Wilson <twilson@redhat.com> (cherry picked from commit a4e49b6b8fcf9acfa4e84c65de19ffd56b9022e7)
