Error Message Traceback Reports
Message Text
Message text is a text string that describes the error condition. The text string may contain detailed
information about the event, including terminal port numbers, network addresses, or addresses that
correspond to locations in the system memory address space. Because variable fields change from
message to message, they are represented here by short strings that are enclosed in square brackets ([ ]).
A decimal number, for example, is represented as [dec].

Error Message Traceback Reports
Some messages describe internal errors and contain traceback information, which provides the stack
trace of the function calls that resulted in the message. This trace helps the engineers track down the
problem that is indicated in the message. You should include this information when you report a problem
to your technical support representative.
The traceback report includes the following sample information:
-Process= "Exec", level= 0, pid= 17
-Traceback= 1A82 1AB4 6378 A072 1054 1860
The numbers that are printed in the message indicate which lines of code caused the message to occur.
