Title:
Nova api service doesn't handle SIGHUP signal properly
Status in Cinder:
In Progress
Status in OpenStack Compute (Nova):
Fix Released
Status in The Oslo library incubator:
Invalid
Bug description:
When SIGHUP signal is send to nova-api service, it doesn't complete
processing of all pending requests before terminating all the
processes.
Steps to reproduce:
1. Run nova-api service as a daemon.
2. Send SIGHUP signal to nova-api service.
kill -1 <parent_process_id_of_nova_api>
After getting SIGHUP signal all the processes of nova-api stops instantly,
without completing existing request, which might cause failure.
Ideally after getting the SIGHUP signal nova-api process should stop getting
new requests and wait for existing requests to complete before terminating all
the processes and restarting all nova-api processes.
