------------------------------------
Summary: 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: 1.11.1, 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
Fix For: 1.8.0
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.
