So ... the plot thickens. My initial analysis was flawed and reload did not in fact address the problem. I was able to observe the neighbors all having issues again and this time I saw that a neighbor relationship was stuck in 'loading' state. After a lot of looking around, I determined that the interface and ip mtu both were 9216. I suspect that this mtu was too big and that my igp had grown to a point where fragmentation was needed but due to an incorrect mtu here, the updates were not working due to full size packets. I added 'ip mtu 9000' and the problem has not come back since (>10 hours now).
