Intercepted event sink error: {}

sbotkine — Fri, 14 Mar 2014 10:31:57 GMT

Hello,

I've developped my first bundle on my HP VAN SDN Controller 2.0.
Everythings seams working correctly but I have the following WARNING message:

hp.sdn.event EventDispatch-13-thread-1 Intercepted event sink error: {}

I dont' understand the meaning of this warning. How can I investigate ?

Regards,

Serge

I've stopped my bundle (that means the controller only have default bundle).

I've restart the controller.

But the warning is still here. Here is the full log I can read every minute in the log.log file:

[2014-03-22 09:49:28.711] WARN EventDispatch-13-thread-1 hp.sdn.event DE0005I Intercepted event sink error: {} java.lang.NullPointerException: null

Why do I have such warning ? What does "event sink error: {} means ?

Hello sbotkine,

This error is caused by an event being sent by node-manager, with node whose IP is null. This is not supposed to happen since hosts without IP should not be in the system.

This will be fixed in future release of the Controller.

Thanks,

During a dhcp request, generally the IP host src is 0.0.0.0.

Do you mean that alert is generated each time a client make a dhcp request for the first time ?

Hello Serge,

Since this error is caused by an event being sent by node-manager, with node whose IP is null and during dhcp request generally IP host src is 0.0.0.0. so this alert is generated each time a client makes a dhcp request for the first time.

This will be fixed in future release of the Controller.

Thanks,
