I have similar issues, it can happen many times a day, or there are few 
days without a problem.
There is no "route monitor" output when it happens.
"fstat | grep route" periodically gives just ntpd and bsnmpd. I turned 
it off, no change.
I tried to turn TSO on all em interfaces - no change.

Three routers with similar setup and problem of changing default gateway 
or static routes:
- 9.0-RELEASE-p1 FreeBSD (amd64)
- IPFW & dumynet for shaping
- PF for NAT and filtering

I do not use MPD. However I do use PPPoE in my network, terminated at 
Mikrotik Routerboard and then routed to FBSD.

Sorry for my poor english.
Best regards!
