Deregistration of listener with id failed

[Prashant choudhary]

Hi,

I have three member node running on the same or different machine.  I have java client which is adding a listener to a map.

getRequestCache().addEntryListener(new MyTestRequestEntryListener(), true);

Order of start 

Node1

Client

Node2

Node3

My java client is able to receive all the events on the particular map. If I forcefully stop Node1 then I get the exception below and java client not able to receive the events. But it works fine if I stop Node2 or Node3.  It looks like if a client is connected to particular cluster member then and not able to failover to another member.

Is someone also faced this issue? Any solution to overcome this?

I am using the latest version 3.7.4.

Hello,

The listener registration mechanism changed at the latest releases, so I strongly recommend using the latest releases.

Regarding this log at 3.7.4, this log may be OK which is an information that during reregistration, the listener could not be deregistered from the member (is this 2e813fc6-ad8e-4cf3-a9f6-a9fdb06e9295 Node 1 uuid?) But following this, the reregister should continue and register to the existing members. You should be receiving the events unless those registers also failed. Do you have any additional log to suggest that the register also failed?

It needs more investigation but lets also check if you get the problem when you use the latest release jar.

Regards,
