> Key: STORM-1928
> URL: https://issues.apache.org/jira/browse/STORM-1928
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-multilang
> Reporter: Jungtaek Lim
> Assignee: Jungtaek Lim
> Priority: Critical
> Fix For: 2.0.0, 0.10.2, 1.0.2, 1.1.0, 0.9.7
>
>
> 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.
