When I see this behavior it also see timeouts on snmp particularly on the ciscoBgp4MIB tree, which makes sense. Running “show snmp trace slow oids” confirms this.

We've swapped out a ton of ASR9001's as they were causing a massive
amount of BGP Refresh messages to peers, spiking their CPU. It was due
to the slowness of the box on our end, as the BGP table has grown, the
number of peers has gone up and it can't keep up.

Shame, since the box, like the MX80 and MX104, has plenty of forwarding
performance left.

We've moved to the MX204.

You might be able to resolve your CPU issues, but you're just delaying
the inevitable.
