When a process ends abnormally (an abend or dump), an entry is made in the syslog, or the Windows Event log. If there is more data to be written than is appropriate for the log, a new file is created to contain it, and the log entry tells you the file name. You need to send the file to your IBM Support Center for analysis.
Abend files are never generated during normal operation; always involve your IBM Support Center when they do occur.
The abend file might provide a stack for the failing thread; this might help you to identify problems in the plug-in code when an abend occurs here. In which case, for z/OS, this stack will be available in a CEEDUMP file in the same directory as the abend file by default.
Periodically clear any unwanted abend files from the errors or z/OS log directory. You can do this by moving the files to an archive, or by deleting them when they are no longer needed. This ensures that the workpath does not become full; in extreme conditions, your system performance can be degraded if significant space is being used up with old abend files.
