Question
Why there is hourly JBoss GridDiscoveryServiceJob error in caIntegrator's server log?
The question was posted in the caIntegrator user forum.
Answer
...
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 failure in the attempt to reconnect shouldn't impact performance.
Error Explanation
There are 2 error message shown in that KC post:
...
- The second message is due to caIntegrator trying to connect to the NBIA grid service and not be able to reach the NBIA grid service. This would happen if the user's NBIA installation was behind a firewall or if the grid index service was down.
