> are blocked (b) Content Repository at 100%
> ---------------------------------------------------------------------------------------------------------------------
>
> Key: NIFI-8481
> URL: https://issues.apache.org/jira/browse/NIFI-8481
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core UI
> Affects Versions: 1.13.2
> Reporter: Eric Detwiler
> Priority: Minor
>
> We experienced an issue with NIFI where there were
> 1) No errors/warnings in the log file (however, we did see INFO messages)
> 2) No Errors on the UI
> 3) All TimerDriven Threads were occupied (Stack dump revealed they were
> waiting to write to the archive)
> 4) Files sitting on disk when GetFile should have been processing
> Basically NIFI was completely locked up waiting for space in the archive
> content repository to be cleared out. But was not obvious since disk usage
> was extremely high.
