Public bug reported:
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.
Public bug reported:
VN added support for aging out MAC_Binding entries [1][2]. Without this

On a large OVN DB, frozen_row() calls for the event notification
processing can add 10ms up to 40ms or more depending on the size of the
row (as compared to 4usec for just passing the Row object). This can
easily make startup times w/ large DBs increase by a factor of 3 or
