Following two ways can help you identify the short dump:

•   Restart the system so that profile parameter changes take effect.
•   Reproduce the issue (logon to the system).
•   The popup "rabax during sapgui logon" should disappear now and you are able to:

       - see the dump directly.

       or

       - get more information about the short dump from corresponding dev_w* trace.
