> Multithreading issue in notify
> ------------------------------
>
> Key: NIFI-14512
> URL: https://issues.apache.org/jira/browse/NIFI-14512
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.28.1
> Reporter: Geoff Greene
> Priority: Major
> Attachments: Geoff.json
>
>
> I have verified this in 1.28.1. I have not tested or verified it in any
> other version.
>
> See the attached flow.
> Setup:
> 1) Run the generate til there are 10,000 flow files, then run UpdateAttribute
> 2) Run the wait til all 10,000 flow files are waiting (on TWO signals)
> 3) NOW run the Notify. It should send two signals (one for each flow file).
> All the waits should then release. They do not. Only a few do, and the
> number is variable. Note that the Notify is set to 5 threads. IF you set the
> notify back to ONE thread, all the notifies work fine, and all the waits
> release. Instead, with 5 notifies, they will expire after one hour.
