JBoss AS 7 is stopping every 15 minutes - jboss

Question

JBoss AS 7 is getting stopped after every 15 minutes.
Please tell me where the configuration for this is so that i can remove it. I want the server to run until I use ./stopserver.sh to stop it.
If i run server from command prompt and do transaction after keeping it idle for 1 hour only the first hit fails with the following errors:
{03:37:31,526 INFO [stdout] (http--0.0.0.0-8080-1) above to execute

Answer 1

Server was stopping because of Time -out hence we need to add " deployment-timeout" in standalone.xml as given below:
<subsystem xmlns="urn:jboss:domain:deployment-scanner:1.1">
<deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000" deployment-timeout="1200"/>
</subsystem>
