Vinicius Zolin commented on NIFI-7114:
--------------------------------------
I've annexed 4 files to help with this issue.
[^lsofBefore.log] and [^lsofAfter.log] are lsof output some hours apart. Those
are not the best examples but I will reboot NiFI and collect better data.
[^source.xml] and [^destination.xml] are the flows that I'm using. Those should
help replicating the problem.
Source is just a sample flow generating provenance records to be parsed by
destination.
Source will not show the problem, but destination should.
> 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
> Fix For: 1.8.0
>
> Attachments: destination.xml, lsof.log, lsofAfter.log,
> lsofBefore.log, 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.
