Most of the time it is fine, but occasionally the SA cache seems to
suffer (perhaps from really fast MSDP flapping, entries time out before
they can ne updated ??).  Examples of "dips" in our SA entires can be
seen in the current SA graphs at:

On the whole we live quite OK with these messages being a nuisance in
our logs.

If someone from Cisco is on the list, perhaps we could work together to
pinpoint the cause of the flaps and request a code-fix ??  I am willing
to suffer some pain to remove/reduce the error messages ...
