1239   Nested exceptions limit exceeded

Cause

This error occurs if the maximum number of nested exceptions is exceeded (the limit is currently 20).

A common cause is when an exception handler itself raises further exceptions; for example, if the original exception handler displays a message box or dialog on the client workstation and the original exception caused a thin client disconnect, this then causes a further exception, and so on.

Action

Check your application messages log (the log file with the name of the application that raised the unhandled exception). A history of nested exceptions is shown in the Exception Stack History section of the application messages log file. The initial exception that triggered the sequence of nested exceptions is listed at the base of the exception stack. Knowing this may help you to determine the best way to deal with the problem.
