Bird 1.4.0 - Process suddenly disappeared

[Nikita Borisenkov]

Hello, today we have a problem with our network. When connectivity 
problems between routers were solved, we noted that bird process not 
running.
The process  suddenly disappeared without any messages to logs.

We use bird 1.4.0
It can be a problem which was solved in commit 
864f52a5f4c47ac8dc44a8808beb7f038cbf9899 - "Fixes nasty bug in BFD"? or 
this is something else?
