We too got hit here in Geant-2 land this past Thursday. We have sap listen on a number of interfaces.

You can see it via our router CPU graphs:
http://noc.ilan.net.il/stats/ILAN-CPU/gp0-cpu.html
http://noc.ilan.net.il/stats/ILAN-CPU/tel-aviv-gp-cpu.html
Happened around 8pm (GMT+2) here in Israel.

We have filters in place but they didn't help :-(

From our core router (gp0):
mls rate-limit multicast ipv4 ip-options 500 50
ip multicast boundary boundary-filter
ip igmp access-group igmp-join-filter
ip igmp limit 1000
!
ip access-list standard boundary-filter

What am I missing?

On our msdp router (mcast) which seemed to fair better based
on the CPU graphs
http://noc.ilan.net.il/stats/ILAN-CPU/mcast-cpu.html:

ip multicast boundary boundary-filter
ip multicast rate-limit in 40000
ip multicast rate-limit out 40000
ip igmp access-group igmp-join-filter
ip igmp limit 1000

Actual Cisco IOS suggestions most welcome.

Thanks,
Hank
