Alexander Lapin commented on IGNITE-25611:
------------------------------------------
The reason is likely following:
1. NodeA (5003) starts.
2. NodeB (5004) starts.
3. Leader is elected, let's say that NodeA is a leader.
4. Because NodeC(5005) startup hangs a bit, leader ping message to NodeC may
fail and in a rare unfortunate event will be accumulated by log inspector.
5. NodeC starts.
6. NodeB stops.
7. Leader failed to send message to B which is expected.
As a result there are two connectivity related records in log from step 4 and
step 7. However within test we expect only one from step 7.
In case of two nodes in the group, situation explained in step 4 becomes
impossible, thus we use 2 nodes only.
