Joe Witt commented on NIFI-7114: -------------------------------- There is no evidence yet that this is a framework issue needing to be resolved. What does seem possible though is that scripts used in ExecuteScript or ExecuteScript itself might leak handles to certain streams (input/output/error). This might also occur with ExecuteStreamCommand/etc.. as well. But this needs more investigation in general. Going to remove 1.11.2 fix version so we can get the rest of the good fixes out there > 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, lsof.log, lsof.zip, lsofAfter.log, > lsofBefore.log, openFiles.xlsx, 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
