ccr lockup in 6.4

Just saw our CCR max to 100% CPU for the first time…

Was delivering about half the traffic, denying SSH connections, and interface window in winbox was empty. log file was complaining about discarding a locally originated packet, but no changes had been made to ospf. Attempting a reboot took three attempts and about 3 minutes before it actually did the reboot.

Reboot brought all services back to normal. Anyone else actually seen a CCR go to 100% proc util?
