I wonder where and how to catch that "lost/timeout connection".

I guess transaction timeout is the important one - because it will be shorter than the others?

I  have tried both dberror and error event in u_dw and also tried error event i n_tr  (dberror) or  application (systemerror)

I guess the error arises because of a transaction object no longer valid or maybe NULL ?

Another Question/answer suggested testing error 08051

Maybe the error is happening on some Embedded SQL statement?

If you want to disconnect after an hour of inactivity, use the Idle event of the application object. See: https://community.appeon.com/index.php/qna/q-a/code-for-application-close-after-x-minutens-of-no-activity?limitstart=0#reply-31773

Ok - will use Idle() event instead of catching timeout error from Powerserver, but I guess at some point users should be able to catch those errors ?

Hi Håvard,

If the "Predefined message not found -1" message on the screenshot is not generated by custom code and you are unable to catch this error, I suggest that you submit a ticket via our support portal at https://www.appeon.com/standardsupport/newbug and send a code sample there.

Regards, Logan
