 I see this too on latest asterisk versions. The fast solution found - 
open 'asterisk -R' on some console - all the 'queued' messages begin to 
deliver as fast as should.

Strange, it doesn't depend from the console loglevel - the problem 
remains even if the console is silent while BLF is changing.
