[CentOS] Need help to understand about some lines which are printing on console

Hi,

Some lines are printing on console:
[CCafException] CAppConf@[1711]: CommAmqpListener: [CCafException] CAppConfig:: getString() Required config parameter [amqp_password] is missing from section [c ommunication_amqp]

Can you help me to understand why we are getting these lines on console?
How we can remove these lines from the console?

Please suggest.

Thanks & Regards,
Shagun
