   Description

   The SDM system executes an several places external scripts. If such a script
   could not be executed the real error message is not reported.

   I had a problem on a host which ran out of memory. I tried to start a sdm jvm on
   this host with

   % sdmadm -d suj
   jvm         host   result message

   The error message does not give the user any hint what's the real problem is.
   The error message “arch script has been interrupted” is definitely wrong.

   Evaluation

   This issue has only limited impact on the functionality system. However for
   support cases it is be vital to get correct error messages.


   Suggested Fix/Work Around

   We have no workaround for this issue, it must be fixed.

   Analysis

   The native method UnixPlatform_executeNativeScript does not report the error
   message if popen fails.
   We should allow that this method throws an IOException in this case. The message
   of the exception should be the popen error message from errno.


   How to test

   remove the executable permission from the arch script (<dist>/util/arch)
   start a sdm jvm
   You will get the above error message
