One of our Customers got an error when starting the tomcat service, CRM 7.2d:
Fehlercode 0 / Error code 0, the tomcat commons-daemon.log showed "[error] Failed creating java"
I checked the registry at
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\CRMTomcat7\Parameters\Java
The Key "Jvm" was set to "auto".
I changed the Value to the path of the jvm.dll provided with the CRM installation, in my case "D:\Sage\Services\JRE\jre7\bin\client\jvm.dll".
After saving changes, the tomcat Service was starting again.
I still have no clue, why the service stopped working at the beginning.
Hope this helps.
