Add timeouts to avoid GetSplunk processor hanging

I configured GetSplunk to run on cron schedule every 2 min, sometimes when there's no data to retrieve from Splunk, the job thread hangs with no issues or outputs and keeps running, blocking the new scheduled jobs from starting until I stop--> terminate --> start processor.

 
1- Why this happened in the first place, that the threads of GetSplunk kept hanging
2- How to over come such situation in the future? we need to either be notified by some kind of log message or the threads should terminates on their own.
3- If a thread was hanging, then why subsequent threads didn't execute
 
I also believe that adding a timeout property to this processor is important
