How do you tell that it keeps dieing?
It should output an error in any case - please look under
tomcat/logs/ there are the files
catalina.out and l
ocalhost-xxxx.txt, try to delete them, restart QM, when it crashes, look for an error there (an error is called an Exception in Java parlance).
[Please post only the error here, as the logs are very verbose]
Any other info you may have - screenshots, reports, whatever. 10 minutes are really a symptom that something is going very wrong
