java - Tomcat7 doesn't start and show no error message -

i'm facing problem trying start/restart tomcat7.

when start/restart, service seems starting/restarting ok:

* stopping tomcat servlet engine tomcat7 [ ok ] * starting tomcat servlet engine tomcat7 [ ok ]

however, checking log, found this:

oct 22, 2014 11:48:14 org.apache.coyote.abstractprotocol init info: initializing protocolhandler ["http-bio-8080"] oct 22, 2014 11:48:14 org.apache.catalina.startup.catalina load info: initialization processed in 721 ms oct 22, 2014 11:48:14 org.apache.catalina.core.standardservice startinternal info: starting service catalina oct 22, 2014 11:48:14 org.apache.catalina.core.standardengine startinternal info: starting servlet engine: apache tomcat/7.0.52 (ubuntu) oct 22, 2014 11:48:14 org.apache.catalina.startup.hostconfig deploydescriptor info: deploying configuration descriptor /etc/tomcat7/catalina/localhost/manager.xml

and nil else happens. cpu seems ok , memory too. got stuck in point.

this issue appears because no alter made, no updates on tomcat or changes in artifact i'm trying deploy.

what problem?
