Resolution

You can have a look at the following documentation.

http://help.k2.com/onlinehelp/K2blackpearl/ICG/current/webframe.html_MSMQ.html_tracksearch=Message queuing

http://community.k2.com/t5/K2-blackpearl/An-error-has-occurred-System-Messaging-MessageQueueException/ta-p/77308

Also make sure the appropriate permissions have been set to the event bus queue and eventbus queue error as well after this the error should no long appear.

In this case make sure the service account itself has full control to MSMQ and the queues as mentioned above.
