Dropped netlink updates during scans

Hi, We’re using BIRD to redistribute routes that are programmed into the Linux kernel for routing to local containers or VMs. We set a scan time in the kernel section of the config in order to notice when routes are removed. Normally, BIRD picks up routes that are added extremely quickly. However, if a route is added during a scan, it seems to be missed and it is not picked up until the next scan, many seconds later. Is this a known issue; is there a workaround? For example, is there a way to tell BIRD that a route was removed from my external code rather than having it poll? Thanks, -Shaun
