Description

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.
