Why ospf restart? Dead interval 4sec not been reached. Well, it is counted from the last received hello, so you have to add 'packets' to OSPF debug to see when it started.
Also timers in BIRD have generally second granularity, so 4 sec timer may timeout in some cases in 3.1 sec. And there is also one minor bug that may cause some timers to te triggered ~1 s earlier.
So all these factors together, 4 s (or smaller) dead timers in BIRD may be unreliable. I would suggest at least 8-10 s.
