Answer

Background

caIntegrator tries at every hour to connect to the caGrid index service in order to find caIntegrator client services such as the NBIA grid service and other grid services caIntegrator can connect. As a result of this automatic pinging and re-connect, once a grid service such as an image data source is added to a study, the new grid-based image data source will be shown in the dropdown menu as a part of all available image grid data sources. If the attempt to reconnect results in an error , then the dropdown menu will only show the default grid data source that caIntegrator knows that exists, such as the NBIA hosted at NCI. Either success or failture failure in the attempt to reconnect shouldn't impact performance. Right now the caIntegrator team is working to either suppress that warning or only show it once a day so it isn't quite as annoying.

Error Explanation

There are 2 error message shown in that KC post:

• The 1st first message is due to caIntegrator being unable to reach the grid index service. This would happen if the users caIntegrator installation was behind a firewall or if the grid index service was down. The grid index server is contacted once per hour.

• The 2nd second message is due to NBIA being unable to register itself in the grid index service. This would happen if the users NBIA installation was behind a firewall or if the grid index service was down.
