> Cluster loses connectivity after some time

> Key: IGNITE-21010
> URL: https://issues.apache.org/jira/browse/IGNITE-21010
> Project: Ignite
> Issue Type: Bug
> Reporter: Roman Puchkovskiy
> Assignee: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
>
> When running ItSqlLogicTest (where the cluster consists of 2 nodes),
> sometimes nodes lose each other (i.e. both think that anoher node has left
> the physical topology).
> This is because ScaleCube cannot perform ping roundtrip (send ping request +
> receive ping response) in 200ms, and this state holds for 10 seconds.
> Either this is because the timeout of 200ms is too low, or there is something
> summing up (like a leak, or a message that blocks the processing for too
> long). This has to be investigated.
