> The following 2 tests frequently hang:
> org.apache.ignite.internal.processors.igfs.IgfsTaskSelfTest#testTask
> org.apache.ignite.internal.processors.igfs.IgfsTaskSelfTest#testTaskAsync
> Also that happens on public TC.
> Thread dump does not show any specific reasoon of stuck, but it frequently contauns sttack like this:
