> Key: IGNITE-4381
> URL: https://issues.apache.org/jira/browse/IGNITE-4381
> Project: Ignite
> Issue Type: Task
> Components: general
> Reporter: Semen Boikov
> Fix For: 2.2

>
> If internal threads execute blocking operation this can cause starvation and
> hangs (example of issue https://issues.apache.org/jira/browse/IGNITE-4371).
> Ideally we need a way to 'automatically' find all such places in code,
> straightforward idea is add assert in GridFutureAdapter.get - assert should
> fail if it is called by system thread and future is not finished. At least
> one issue here is that currently system threads can be blocked on operation
> on utility/marshaller cache, so assert should also take it into account.
> Another idea is execute tests with number of threads in all pools = 1, this
> also should reveal issues with blocking calls.
