             Summary: IGFS: test org.apache.ignite.internal.processors.igfs.IgfsTaskSelfTest hands on WiFi newtwork
                 Key: IGNITE-3922
                 URL: https://issues.apache.org/jira/browse/IGNITE-3922
             Project: Ignite
          Issue Type: Bug
          Components: IGFS
    Affects Versions: 1.7
            Reporter: Ivan Veselovsky
            Assignee: Ivan Veselovsky
             Fix For: 1.8


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:
