Running RDz 9.0.1 - Trouble running under z/Linux in the background...

I am running RDz 9.0.1 under RedHat 6.4 (s390x).  When I do a   rsed.sh RedHat   and run it in a foreground windows the server start and runs OK. 

HOWEVER , when I do a   rsed.sh RedHat &  to get it to run in the background , I get this in the rseserver.log:
[root@b23zdrwizapp01 log]# cat rseserver.log

I don't get a  server started message. 

And the  ps aux   shows that the   rsed.sh  task is marked terminated.

I believe I have all the  envvars set up OK ...

Just looking for some insite on this.

Thanks!
