> It affects Storm releases which are greater than 0.9.3 so I didn't set affect version/s. All version lines are affected.
> When nextTuple is not calling at any chances (max spout pending, backpressure introduced at 1.0.0, and so on) multi-lang spout don't receive any message from ShellSpout, thus no messages from multi-lang spout side. (because multilang spout and ShellSpout communicates like ping-pong, unlike multilang bolt and ShellBolt)
> In result, no heartbeat is being marked, and finally raises subprocess heartbeat timeout.
