Just wanted to offer that we run bird on Linux with 100% stability. 150 
days of runtime with no routing table strangeness on one system.

I think the main issue may be that we use bird only with RIP and kernel 
routes. We do not run OSPF. We do however, have route filters (like "import 
where net ~ ...") on imports and exports (which seemed like it was one of 
your questions).

Given the perfect reliability of bird on our similarly-sized network and 
your poor reliability, I wonder if the OSPF protocol is the issue. Not that 
this helps you if you need OSPF, but maybe it provides someone some focus.
