Joe Witt commented on NIFI-7114:
--------------------------------
[~vzolin]what is the simplest flow you can run which reproduces this problem?
Please share the actual flow.xml.gz of that. Ideally it is self contained so
we can run it. Makes its own data/etc.. Please share latest before/after lsof
-p output over time please. Not just the count but the actual output.
Thanks
> NiFi not closing file handles
> -----------------------------
>
> Key: NIFI-7114
> URL: https://issues.apache.org/jira/browse/NIFI-7114
> Project: Apache NiFi
> Issue Type: Bug
> Components: Configuration
> Affects Versions: 1.10.0, 1.11.0
> Environment: Amazon EC2 running either Amazon Linux 2 or Ubuntu 18.04.
> NiFi has been installed with no change to any configuration file.
> Reporter: Vinicius Zolin
> Priority: Major
> Attachments: destination.xml, fifocounts.txt, flow.xml.gz, lsof.log,
> lsof.zip, lsofAfter.log, lsofBefore.log, openFiles.xlsx, reproduction.zip,
> source.xml
>
>
> Since at least version 1.10 NiFi stopped closing file handles. It opens circa
> 500 files per hour (measured using lsof) without any apparent limit until it
> crashes due to too many open files.
>
> Increasing the computer open file limit is not a solution since NiFi will
> still crash, it'll only take longer to do so.
