Maksim Timonin updated IGNITE-25700:
------------------------------------
Description:
Test TcpDiscoverySpiFailureTimeoutSelfTest#testConnectionCheckMessage sometimes
fails. The test checks that during failure detection timeout there are 15-25
ping messages between two neighbors nodes. But sometimes test fails because
there are only 14 messages.
Reason is TcpDiscoveryMetricsUpdateMessage that is sent every 2000ms. Sending
of the message resets a timer used for sending the
TcpDiscoveryConnectionCheckMessage message.
Then in the default failure detection period (10000ms) it can be sent 6 times.
It's OK to await 20 times of the check message, but the reset can drop 6 sends,
and we will get 14 messages.
