Hello everyone.

I was wondering if anyone has seen this and if it is caused by a bug or a
security hole. OSPF process is in an endless loop of errors that I was only
able to fix with a reboot. I could not restart the OSPF process as it would
just hang for 60 seconds and then give up. This problem takes the CPU to
100% when this OSPF problem happens and for whatever reason, happened on
two routers at the same time. I did some searching but was never able to
find an actual answer as to the cause. What I find odd is that two routers
would end up with the same problem at the same exact time if it is a bug
and if it is a security hole, that I was not able to find the details on
it.
