> I was running a NiFi version 1.12.1 without any problems with this regard. Yesterday I updated to version 1.14.0 (really wanted to get fix https://issues.apache.org/jira/browse/NIFI-7849). But now I am in a way worse state. 
> I use InvokeHTTP processor to self-connect to NiFi API to get count of flowfiles being processed by given processor group.
> However this InvokeHTTP started getting stuck. Processor would just spin up a new thread and this will sit there indefinitely (six hours at-least), blocking incoming flowfile. After forceful termination of processor (simple stop is not enough) the flowfile would get released and next start will consume the flowfile just fine. (Timeouts are: connection 5 seconds, read 10 seconds and idle 1 minute.) And of course log is clear of any errors which seems to be connected to this... 
> I had noticed similar issue also with other processors, namely MergeContent processor or ExecuteSQLProcessor - e.g. flowfile gets stuck for 15 minutes (merge bin max age is 5 seconds). After forced termination all starts working (for some time - a few dozens of minutes).
> Oh and in all cases the thread hangs in terminating state (red thread icon with a digit in parenthesis; the digit sits there all the time and wont disappear). Only restart of whole NiFi clears the issue. For some time.
>  
> Maybe some disk I/O issue?
