             Summary: Thread stucks on OnTrigger 
                 Key: MINIFICPP-1692
                 URL: https://issues.apache.org/jira/browse/MINIFICPP-1692
             Project: Apache NiFi MiNiFi C++
          Issue Type: Bug
    Affects Versions: 0.11.0
            Reporter: Eduardo Mota Fontes
         Attachments: config.yml, minifi-app.log, minifi.properties

I've tested minifi 0.11 + Nifi 1.15 and I got warnings that I don't know if it's a version issue.

How to reproduce:
- Download and unpack Nifi 1.15 binary
- Download, unpack and compile Minifi 0.11 source
- Start Nifi with default settings, create a remote input port with name "entrada", start it and connect it to a funnel
- Configure minifi TLS
- Configure minifi's flow (config.yaml) with a ExecuteCommand (find ./ each 30 secs) with success relationship to a RPG pointing to NiFi 1.15 "entrada" input port
- Start minifi

At this point everything is ok. The result of the command "find ./" lands on the NiFi input port and stays in the funnel's queue.

The problem is, if NiFi stops for some reason (I simulate this stopping the input port), I start to get warnings in minifi's log the like:


[org::apache::nifi::minifi::SchedulingAgent] [warning] entrada::onTrigger has been running for 971026  ms in 4d3e32ac-017d-1000-b4b1-e7f36e039202

And if I start NiFi the warnings continue and it never stops. In this state, if I try to stop minifi using "minifi.sh stop" it doesn't stop and I have to kill the minifi's process.
It seems the thread stuck.

I did the same test with 0.10 minifi c++ and the issue doesn't happen. When I stop the input port in NiFi I get this:

[org::apache::nifi::minifi::core::Processor] [warning] Caught "Process Session Operation: Can not find the transfer relationship for the updated flow 89289e16-4d90-11ec-bef4-c0b6f9f714b7" (N3org6apache4nifi6minifi9ExceptionE) during Processor::onTrigger of processor: 4d3e32ac-017d-1000-b4b1-e7f36e039202 (entrada)


And when I started the input port again it came back to work normally.


The issue doesn't happen with MiNiFi 1.15 Java version too.

 

Config e log attached.
