Joe Witt commented on NIFI-9572:
--------------------------------

Hello [~mayki]

In requesting the 'java -version' output you instead appear to have sent the 
output of other bash commands.  Further the link implies you're on JDK 1.8 
update 261.  However, the beginning of the JIRA you suggest you're on update 
311.

In requesting the lsof output periodically as the number of open files grow you 
are instead showing that now nifi fails to start with an open file handle limit 
hit during the startup process.  I again suspect you do not have the proper 
file limit set for the user you're actually running nifi as (which the above 
info implies might be the user 'nifi').  I dont know that the ulimit results 
you've shown are for the user nifi or whether they're for the root user or some 
other user.

It is very difficult to be helpful when the various details don't line up 
because we're not making progress.  I appreciate there is a chance that there 
is some bug in NIFi causing this but at this stage I dont suspect that - I 
suspect environment/config setup not matching what you're intending.

We really need to see full commands/full output at this point to help progress.

I think for me to be helpful via a JIRA here I still need to see:
1. 'whoami'
2. 'java -version' including command entry and results
3. 'ulimit -a' including command entry and results
4. 'lsof -p <pidofnifi>' run every 30 minutes while nifi is running

Thanks
Joe
