Open Stack

I was testing for a bug and suddently all neutron services got corrupted.
Even the VM is soft rebooted and stack is rejoined but all neutron services
are not starting....Any clue how to move forward from this point on, or
clean is the only way?

*DHCP*
python /usr/local/bin/neutron-dhcp-agent --config-file
/etc/neutron/neutron.conf --config-file=/etc/neutron/dhcp_agent.ini
stack at testhavana:~/devstack$ python /usr/local/bin/neutron-dhcp-agent
--config-file /etc/neutron/neutron.conf
--config-file=/etc/neutron/dhcp_agent.ini
