> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Reporter: Andrew Mashenkov
> Assignee: Andrew Mashenkov
> Priority: Major
>
> GridCacheMvccManager.removeExplicitNodeLocks() run synchronously in discovery
> and exchange threads. This introduce unnecessary delays in discovery and
> exchange process.
> Also, this may cause a deadlock on node stop if user transaction holds an
> entry lock and awaits some Ignite manager response (e.g. cache store or dr),
> as manager stops right after last exchange has finished so managers can't
> detect node is stopping.
