Hi Maria,
As these messages are informational in nature (as opposed to 'Warnings' or 'Errors'), they wouldn't appear to be a cause for concern. Depending on the amount of Resources in your environment, these messages appear to correlate with your Application Server's connectivity to them and the activity of the messaging service. Are you experiencing any issues (performance, connectivity, etc.) in Blue Prism that would relate to these messages in the Event Viewer, or are there any related Warnings/Errors there as well?
