With RTC V403  server installed on Linux and Build Agent on z/OS and RDz V900,  I am trying to run a build and it is failing with the following message in the Rdz Log :

* BUILD FAILED

Checked z/OS logs and did not find any error message (security RACF, or any error in z/OS), 

I Tested some other functions like  load zFiles  and this works fine.   I upgraded z/OS Java to 6.0.1  with SR6  ( the latest I found for V6 at the IBM Java site) ,  but the problem is not fixed.

Am I missing something ?  Can you help?
