-------------------------------
Okay. Nailed this.
> ExecPlugin leaks a file descriptor
> ----------------------------------
>
> Key: CHUKWA-229
> URL: https://issues.apache.org/jira/browse/CHUKWA-229
> Project: Hadoop Chukwa
> Issue Type: Bug
> Components: data collection
> Reporter: Ari Rabkin
> Assignee: Ari Rabkin
> Attachments: CHUKWA-229c.patch, crashOnOutOfFDs.patch,
> fixExecFDLeak.patch
>
>
> ExecPlugin never properly disposes of the subprocess's input fd. This means
> we run out of file descriptors eventually.
> This only affects ExecAdaptor; if ExecPlugin is invoked by the inputtools
> framework, the process doens't stay running.
