Joe Witt resolved NIFI-8384. ---------------------------- Resolution: Feedback Received Glad you're all set now. Thanks > NiFi 1.12.1 : Too many open files > --------------------------------- > > Key: NIFI-8384 > URL: https://issues.apache.org/jira/browse/NIFI-8384 > Project: Apache NiFi > Issue Type: Bug > Affects Versions: 1.12.1 > Environment: RHEL 7.8 > java version 1.8.0_281 > Reporter: Roberta > Priority: Major > > Hi All, > Hope everything is fine. I’m writing you as we are experiencing a problem in > Nifi 1.12.1 on a RHEL 7.8 with java version "1.8.0_281" . > It is a single node, secured, without any load balancer upstream. However, it > does have a s2s (it process provenance from another machine), ListSFTP + > FetchSFTP processors as well as the ExecuteStreamCommand processor. > After few days running NiFi suddenly shuts down reporting the following > message: > INFO [main]org.apache.nifi.bootstrap.Command Apache NiFi is running at PID > XXXX but is not responding to ping requests > Looking at the log file we are facing the following WARN: > WARN [NiFi Web Server-XX-acceptor-X@XXXX > -ServerConnector@XXXX\{SSL,[ssl, > http/1.1]}{hostname:9443}] > o.eclipse.jetty.server.AbstractConnector java.io.IOException: Too many open > files > We tried to fix the problem my means of the best practice configurations > ([https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#configuration-best-practices]) > but the problem persists. > After some research we found out that a possible cause might be the use of > the processor FetchSFTP that we use in our flow. It creates always new files > during SFTP connections (https://issues.apache.org/jira/browse/NIFI-7222). We > would like to substitute the .nar file you attached to jira but, > unfortunately, it is no more available. > Based on your experience, is it possible that the bug found in NiFi 11.1.4 > and 1.12.0 could still be present in the 1.12.1? > Thank you in advance for your support and let me know if you need further > details -- This message was sent by Atlassian Jira (v8.3.4#803005)
