When I tried to use the Generic SMPP connector to send a SMS, an error occured saying "ESME Already in Bound State. A bind request has been issued within a session that is already bound." Is this the issue caused by the SMS provider or the ACC confirgrations?

Error Details:
Error 'com.neolane.fwk.core.NlException: [SMPP Connector] Could not bind to SMS-C. Returned command status is 'ESME Already in Bound State. A bind request has been issued within a session that is already bound.'.' while getting a connection to send a message. com.neolane.fwk.core.NlException: [SMPP Connector] Could not bind to SMS-C. Returned command status is 'ESME Already in Bound State. A bind request has been issued within a session that is already bound.'.
