Can not start admin server

Hello support,

Application manager, professionnel edition, version 8.6, is installed on a standalone integration server (Windows 2003 server).
I installed on the same server, an admin server in order to be on Enterprise edition.
The install was performed without problem : i changed the web server port.
But when i try to start admin server when manager is also started, admin server doesn't start and i found this error message on the wrapper log :
"on_exit trigger matched. Restarting the JVM. (Exit code: 1)"
I tried to start admin server when the other Application Manager was in standalone or in manager status ; but it happens the same thing.

Can you help me ?

Best regards,

Karine Dumoulin
