> At the moment, the maximum number of concurrent requests is hard coded in
> {{ThreadPoolRequestReplicator}}
> https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-framework-cluster/src/main/java/org/apache/nifi/cluster/coordination/http/replication/ThreadPoolRequestReplicator.java
> The value is equal to 100.
> In some situations where multiple factors are combined (large cluster, S2S to
> load balance data in the cluster, multiple users accessing the UI), the limit
> can be reached and the UI may become intermittently unavailable with the
> message: "There are too many outstanding HTTP requests with a total 100
> outstanding requests".
> This value should be configurable in nifi.properties allowing users to
> increase the value.
