------------------------------
Hi [~markap14], I have the same problem like Mahieddine.
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:

ID}}
{{10:56:28 UTC ERROR xxxx-xxx-xx-nifi0.xxxx:8443}}

The weird thing is that only some flowfiles are stucked other flowfiles goes
forward in the flows.
How can i fix it?
Any suggestion?
Thank you
