now all nodes have the same issue and after running a day , some nodes will disconnect from cluster, I upload node 2 and node 3's dump file and nifi-app.log, who can help me locate the cause, thanks in advance.

the primary and coordinate node is p-edi-nifi-003:9443

node3 nifi-app.log:

Hi ZhouJun,

 

Have you find a solution to your issue ?

 

I have the problem in my production and staging environnement since few months without any solutions. Network issue maybe ?

 

Thanks for your feedback

Hi,

have you found any solution for this? appreciate if you have any inputs on this regard.

 

 

Thanks 

The issue above, specifically also containing error:

java.lang.RuntimeException: Cannot create negative queue size

seems to have been solved in Nifi v15.1 or v16! 

See [NIFI-9433] Load Balanced Connections hangs / log "Cannot create negative queue size" - ASF JIRA (ap...

 

Myself, I  have an issue in the same high-level error "ConnectionLoadBalanceServer Failed to communicate with Peer node" , but a different (root)cause ( which I'm not sure yet how it is  caused , but must be related to network, our docker-swarm multi-node deployment OR a resource bottleneck):

... ERROR [Load-Balanced Client Thread-7] o.a.n.c.q.c.c.a.n.NioAsyncLoadBalanceClient Failed to communicate with Peer nifi2:8443
java.net.SocketTimeoutException: Timed out waiting for Peer nifi2:8443 

 

Master Guru

@ZhouJun 

I'd recommend upgrading your NiFi to the latest release as you may be hitting these related bugs:
https://issues.apache.org/jira/browse/NIFI-9835
https://issues.apache.org/jira/browse/NIFI-9433
https://issues.apache.org/jira/browse/NIFI-9761

Thank you,

Matt
