[jira] [Created] (NIFI-7114) NiFi not closing file handles

Vinicius Zolin created NIFI-7114:
------------------------------------

             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.
