> --------------------------

> Key: NIFI-9695
> URL: https://issues.apache.org/jira/browse/NIFI-9695
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.13.2
> Reporter: davide
> Priority: Major
> Labels: Cluster, balancer, nifi
> Attachments: activeThread.png, cores.png, flow.png, heapUse.png,

> 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}}
> {{10:56:28 UTC ERROR xxxx-xxx-xx-nifi0.xxxx:8443}}
> {{{}Failed to communicate with Peer xxxx-xxx-xx-nifi2.xxxx:8443 when load

> due to java.io.IOException: Failed to decrypt data from Peer
> xxxx-xxx-xx-nifi2.xxxx:8443 because Peer unexpectedly closed
> connection{}}}{{{{}}{}}}
>
> 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.
