[erlang-questions] Stopping Application in erlang.

[harsha sri]

Hi Magnus,

Tried application:stop, giving me error:

 application:stop(uclient).
{error,{not_started,uclient}}

Actually application got started and its running also. This application i
am running ad rabbitmq plugin and its running also, only thing i need to
stop my application and restart application which i am not able to do.

Regards,
Harsha.
