My additional node is not running instances it shows error status

HI Team,

I have an openstack-essex setup with two servers , my second server with nova-compute service gives me a problem.

I can able to launch an instance and the instance is launched in the 2nd server but the status is 'error', but my first server runs the instances without any issues.

Below is the nova-compute.log of my server-2
