Roman Puchkovskiy commented on IGNITE-26941:
--------------------------------------------
Timeouts from GetMetadataResp do cause some events to be missed, so we don't
update the physical topology. It's not clear why those timeouts happen. We
might try to increase the corresponding timeout to 10 seconds in Raft tests
(it's already 10 seconds in our integration tests starting full Ignite nodes)
