Continuous Error in Message processor log : AbstractRequestListener.onException()

[zubermohammad]

Hi Apigeeks,

We have 2 routers and 2 MPs with a 5 node topology where one of the router is in DMZ.

We are seeing a lot of error logs being written in MPs.

Below are the logs of the two MPs:

MP1 IP: 10.19.3.234

MP2 IP: 10.19.3.237

DMZ Router IP : 10.13.151.13

Where vhdef-out and vhdef-in are virtual hosts defined for inbound and outbound environments.

Does anybody have an idea of this error?

thanks !

Are you sure your vhosts are setup correctly? The uri it's trying to resolve is just /

Found the root cause of this.

Our Load Balancer was polling on the VHOST port to check the state of underlying routers. It was really painful to identify the source IP of the requester in such cases where you don't have any proxy deployed on such path.

I have raised another question related to this same issue here:
