> When BlockSender throws an error because of OOM，the volume reference obtained
> by the thread is not released，which causes the thread trying to remove the
> volume to wait and fall into an infinite loop.
> I found HDFS-15963 catched exception and release volume reference. But it did
> not handle the case of throwing errors. I think "catch (Throwable t)" should
> be used instead of "catch (IOException ioe)".
