Tomcat6 does not restart geoserver

Question

I've been using geoserver for a while, and it suddenly stopped working. I usually restart it by relaunching tomcat6:

sudo /etc/init.d/tomcat6 stop

sudo /etc/init.d/tomcat6 start

I often had to do that because geoserver GWC process was using too much memory. But this times it refuses to restart. I had a look to the geoserver.log: it actual starts, load layers, and the last line is:

2014-12-11 16:44:53,765 WARN [org.springframework.beans.factory.support.DisposableBeanAdapter] - Invocation of destroy method failed on bean with name 'geoServerLoader': org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'GWCLifeCycleHandler': Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

Is it possibly the error preventing geoserver to start? If yes, can someone interpret this error message for me, and give a possible solution?

Note: I tried to remove files in geowebcache, but I still have the problem /geowebcache_data/diskquota_page_store_h2 I restarted the server too.

I found what was the problem: I simply deleted the tomcat6 working directory: $TOMCAT_HOME/work/Catalina To do that:

1. stop tomcat: /etc/init.d/tomcat6 stop
2. delete the working directory $TOMCAT_HOME/work/Catalina . Of course, double check you are in the working directory and not in Catalina application directory!
3. restart tomcat: /etc/init.d/tomcat6 start IT may take a while as it must rebuild the temporary directory. In my case, it did not restart, and I could see that tomcat was not restarted and a PID was already existing (using the command /etc/init.d/tomcat6 status). I simply rebooted my server, to have the pid lock released.
