We have been getting an error prompt/alert in our XPages application at random times:
“An error occurred while updating some of the page…status:12152” and
“An error occurred while updating some of the page…status:12029”
We can’t seem to pin it down to anything. Maybe someone has an idea of what these errors are referring to or maybe how to track it back to something? Thanks.

The HTTP 12152 error usually points to a network connection issue rather than anything specific to the browser or the Domino server.12029 again is down to an inability to make a connection to the server.
It sounds like the network connection is intermittent. I don’t know what tools there are to test that, but I would suggest confirming you have a good, stable network connection between PC and server and that it’s not getting negatively impacted by a firewall.
