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.
