The 3 routes reflectors EU have rebooted thereafter a crash of the OSPF process. The 3 RFs have been updated recently. Awaiting to determine the exact cause of the crash, we will downgrade the RF-2 and 3 to different versions.

the 3 routes reflectors US have rebooted. They're running a completely different version. It seems therefore that the crash is not due to a particular version. We are still working in coordination with cisco in order to determine the exact cause of the issue.

In // of analysing crashlogs of route-reflectors, we are checking the events happening on the backbone during the crash. The 6 route-reflectors have crashed at 01:09 (CEST), but other routers have crashed a bit before that:
- fra-1-6k: 00:01
- gsw-3-4m 00:02
- rbx-s18 00:03
- bhs-4a 00:01
- rf-1/2/3/4/5/6 00:09

We are heading to a general issue on the backbone on OSPF. we are carrying on researches.
