thang nguyen dinh commented on NIFI-8541:
-----------------------------------------
we're have 2 NiFi cluster
* one has 5 server on centos 6 , lsof | wc -l show normal with about 12k
opened file
* one has 3 server on centos 7 and there are more than 800K opened file
related to nifi, i don't understand
I setup new standalone nifi which I show lsof to you, I think this issue is not
relate to flow.xml.gz
And if " It seems like the parent process id and the child process id are
repeating in patterns as if tons and tons and tons of instances are being
launched", is it normal? Thank you.
> NiFi open too many library files on centos 7
