Taras Ledkov commented on IGNITE-3694:
--------------------------------------
Root cause:
The file lock is released before the batch is finished at the
*IgfsOutputStreamImpl.close()*.
In this case the *IgfsMetaManager.appendDual* acquires the file lock before the
previous batch is finished.
> IgfsLocalSecondaryFileSystemDualAsyncSelfTest.testAppendConsistencyMultithreaded
> hangs.
