Tomcat won't stop or restart

I tried stopping tomcat. It failed with this message:

• Tomcat did not stop in time. PID file was not removed.

I then tried again and got this:

• PID file (/opt/tomcat/work/catalina.pid) found but no matching process was found. Stop aborted.

I then tried starting tomcat in debug mode and got this:

• PID file (/opt/tomcat/work/catalina.pid) found. Is Tomcat still running? Start aborted.

I them deleted /opt/tomcat/work/catalina.pid and tried restarting and got this:

• $CATALINA_PID was set (/opt/tomcat/work/catalina.pid) but the specified file does not exist. Is Tomcat running? Stop aborted.

Anyone know how to get tomcat restarted?

It seems Tomcat was actually stopped. I started it and it started fine. Thanks all.
