[jira] [Created] (NIFI-4153) Site-to-Site causing "There are too many outstanding HTTP requests" error message

Mark Payne created NIFI-4153:
--------------------------------

             Summary: Site-to-Site causing "There are too many outstanding HTTP requests" error message
                 Key: NIFI-4153
                 URL: https://issues.apache.org/jira/browse/NIFI-4153
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.3.0, 1.2.0
            Reporter: Mark Payne
            Assignee: Mark Payne
             Fix For: 1.4.0


When using site-to-site in cluster, we sometimes see the following error message showing up in the log:

{code}
2017-07-05 16:11:12,452 INFO [NiFi Web Server-318] o.a.n.w.a.c.IllegalStateExceptionMapper java.lang.IllegalStateException: There are too many outstanding HTTP requests with a total 100 outstanding requests. Returning Conflict response.
{code}

Once this occurs, it keeps occurring, sometimes making the UI unusable until the nodes are restarted.
