Description

Here are the logs [link](https://drive.google.com/file/d/1uNH-A3MEWQddJgnprCVhhwLFgk0_FkOf/view?usp=sharing).

The 2283242'th block is generated at 2019-07-30 10:37:49+09:00.
The 2283241'th block is generated at 2019-07-30 10:37:25+09:00.

The "m-eu-central-1-3" node couldn't collect all the precommits of 2283241'th block. So the node generated 2283242'th block too late. This caused view changes.

Research direction

Start by reviewing the linked logs around blocks 2283241 and 2283242, focusing on m-eu-central-1-3 and the missing precommits. Trace where message delivery and view changes are handled, then verify that all required precommits arrive before the next block is generated and that the failure no longer causes a view change.
