Dominik Stadler commented on EXEC-59:
-------------------------------------
Isn't this the same as EXEC-57, the patch that is available there allows to
make PumpStreamHandler.stop() return after some timeout instead of waiting
endlessly in some cases.
> execute() does not return if executed process spawned other processes

> Key: EXEC-59
> URL: https://issues.apache.org/jira/browse/EXEC-59
> Project: Commons Exec
> Issue Type: Bug
> Affects Versions: 1.1
> Environment: Linux x86_64
> Reporter: David Tombs
> Priority: Minor
> Attachments: spawner.sh
>
>
> When executing a process that spawns other processes,
> DefaultExecutor.execute() does not return until these secondary processes die.
> This is a problem for me because I am executing a long-running service that
> uses long-running helper processes. I want to know if the service process
> crashes (which leaves the helper processes running), but I never get any
> notice because execute() does not return. It blocks while calling
> PumpStreamHandler.stop().
