Just a "bit" unresponsive? I usually see the router essentially just
"stop" for 30-40 seconds and pass zero traffic, and drop all it's BGP
sessions too. And occasionally the online insertion will be followed by a
watchdog reload when something doesn't go right.

My recommendation: schedule a maintenance window, then use OIR. If it
works, you're fine, but if it doesn't you won't get yelled at (as much :-)
because you scheduled the downtime.
