Traffic server closing the session error

Hi,
I am experimenting with balancer plugin and I was able run balancer with  'roundrobin' policy. Even I have created 'weighted roundrobin' and 'random'
 policies and all were working fine.
But today when I am trying to run, I am getting '404 not found' or 'requested resource not found in Accelerator' responses at the client.

This is the output of trafficserver with -T http option:

Even I pulled from GIT and reinstalled with --enable-experimental-plugins configuration.
But I am getting the same error. The traffic server often stop working.
Even normal remapping also not working.
May I please know the reason for the error.

Thanks
