--------------------------------------
[~joewitt]
$java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3~18.04-b08
Open JDK 64-Bit Server VM (build 25.242-b08, mixed mode)
I've tried changing to Java 11 but had the same results.
It is a single node, unsecured, without any load balancer upstream. However it
does have a s2s (it process provenance from another machine).
lsof output is attached. [^lsof.log]
> 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: lsof.log

>
> 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.
