Hi, Team, We are using NiFi 1.3.0 and yesterday our NiFi server doesn't response anymore. The root cause is that the NiFi service opens too many files (about 1,000,000+ files)
Further investigation shows that most opened files are jar files in nar bundles (about 980,000+ files) Same jar file in a nar file was opened multiple times without closing any of them. e.g. I found file /opt/nifi/nifi-1.3.0/work/nar/extensions/nifi-websocket-services-api-nar-1.3.0.nar-unpacked/META-INF/bundled-dependencies/nifi-utils-1.3.0.jar was opened several times without closing. Are those jar files loaded by NarClassLoader and why they are opened so many times? Any solution to this issue?
