In networkdb we should ignore delete events for entries which doesn't exist in the db. This is always true because if the entry did not exist then the entry has been removed way earlier and got purged after the reap timer and this notification is very stale. Also there were duplicate delete notifications being sent to the clients. One when the actual delete event was received from gossip and later when the entry was getting reaped. The second notification is unnecessary and may cause issues with the clients if they are not coded for idempotency. Signed-off-by: Jana Radhakrishnan <[email protected]>
