Any outside ping appears to flap

A few months ago I had a CCR1036 configured just fine with BGP with a public AS getting a full route table in a lab. I let it sit up until recently and now it appears like any outbound pings from the CCR experience roughly 50% loss. It’ll be successful for one minute, then completely time out the next. Pinging to the CCR’s public IP is always successful.

I’m using one Peer and no custom routes. I’ve tried firmware versions 6.20, 6.19, and 6.04. All yield the same results. Any ideas?

I figured this one out. After taking a look at the route filters in place, I noticed our (now offline) Edge 2 was in “Set In Nexthop” for the inbound BGP filters along with our Edge 1 router. After taking Edge 2 out, everything works great.
