Elli Schwarz commented on NIFI-7200: ------------------------------------ [~joewitt] Thank you for continuing to help us with this issue. We are not using a Nifi cluster. Java version output: OpenJdk 64-Bit Server VM (build *25.242-b08*, mixed mode) Running *CentOS Linux 7.7.1908*, kernel *3.10.0* Nifi version: *1.11.0* and our nifi.remote.input.socket.port=8444, and nifi.remote.input.http.enabled=false When we used Nifi 1.9.2 we did not have this "open files" issue but we were forced to upgrade Nifi when our system automatically upgraded Java from 1.8.0_232, because of NIFI-5952; after the Nifi upgrade to 1.11.0 we started experiencing this "open files" issue. I don't have any DistributedMapCacheClientService running on this box. We have a lot of site-to-site activity to and from this box. We have 15 running remote input ports, and 2 remote output ports. We have 12 "Transmitting" remote process groups. Current LSOF output running lsof -p <pid>| tr -s " " | cut -d" " -f5 | sort | uniq -c {{...}} {{11 FIFO}} {{18000 IPv4}} {{9246 REG}} {{...}} We currently have *17,670 lines* from *lsof* with output similar to the following: {{... IPv4 ... ... TCP <url1>:<port> -> <url2>:pcsyn-http (CLOSE_WAIT)}} where <url1> is the public IP of the Nifi server I'm running this on, and <url2> is the url set in a remote process group we use to receive data from the Nifi on <url2>. Just checked again after about 20 minutes, and we now are up to *18,034* lsof lines as above - and I'm still watching this number grow every few minutes! Output from netstat -nap |grep <pid> |wc -l is *18,152* for the following line: {{tcp ... <private ip of url1> <url2>:8444 CLOSE_WAIT <pid>/java}} I hope this info gives you some more insight! Thank you very much for looking in to this issue. > IPv4 socket resource leak > ------------------------- > > Key: NIFI-7200 > URL: https://issues.apache.org/jira/browse/NIFI-7200 > Project: Apache NiFi > Issue Type: Bug > Reporter: Joe Witt > Priority: Critical > > https://issues.apache.org/jira/browse/NIFI-7114?focusedCommentId=17044888&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17044888 -- This message was sent by Atlassian Jira (v8.3.4#803005)
