> HandleHttpRequest does not receive HTTP request
> -----------------------------------------------
>
> Key: NIFI-8453
> URL: https://issues.apache.org/jira/browse/NIFI-8453
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.13.2
> Environment: Linux CentOS 7.5
> Reporter: Belkacem D
> Priority: Critical
>
> After starting Nifi, HandleHttpRequest thread remains blocked and does not
> receive HTTP requests.
> A listening TCP socket is openned, a new request opens a TCP socket and data
> is buffered.
> But HandleHttpRequest does not receive the request and the process thread is
> blocked.
> No errors are raised in Nifi logs.
> Restarting Nifi does not always solve the issue.
> Finally, note that this bug was not encountered with Nifi 1.13.0.
