David Handermann commented on NIFI-9695:
----------------------------------------
[~vadidde] The release for 1.16.0 should be available soon. The errors you
describe should be addressed in 1.16.0, and could be tested in the current
release candidate version. Due to the nature of the problem described, there
do not appear to be any other workarounds.
> Load balancing not working

> I have a 3 nodes cluster(as you can see on attached images) with a connection
> with a Load Balance Strategy set to Partition by attribute, sometimes some
> flowfiles get stuck in this connection (see image1). Furthermore we have this
> log error in bulletin board
> {\{10:56:28 UTC ERROR xxxx-xxx-xx-nifi0.xxxx:8443 }}
> {{Failed to receive FlowFiles for Load Balancing due to
> org.apache.nifi.controller.queue.clustered.server.TransactionAbortedException:
> Attempted to receive FlowFiles from Peer xxxx-xxx-xx-nifi2.xxxx for
> Connection with ID 0c20343f-f63d-1ef1-8da0-6d3cb9fc670d but no Connection
> exists with that ID}}

>
> The weird thing is that only some flowfiles are stucked other flowfiles goes
> forward in the flows.
> I think this bug is the same of
> https://issues.apache.org/jira/browse/NIFI-9574, I post a comment in
> NIFI-9574 but I have got no answer.
