Not sure that whether I have resolved the problem completely or not, but
now its working with the following changes in heat.conf file:

#[profiler]
#profiler_enabled = True
#trace_sqlalchemy = True

Just commented the above and restarted the service and now its working. If
there is any suggestion or any other input/advice in general then please
drop me an email.

Thanks & Regards,
Mohit
