Summary: Fix flaky test
TcpDiscoverySpiFailureTimeoutSelfTest#testConnectionCheckMessage
Key: IGNITE-25700
URL: https://issues.apache.org/jira/browse/IGNITE-25700
Project: Ignite
Issue Type: Bug
Reporter: Maksim Timonin
Assignee: Maksim Timonin
TcpDiscoverySpiFailureTimeoutSelfTest#testConnectionCheckMessage
test is sometimes fail. 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.
