Why my Tomcat 7 stop working after deploy

I have a grails app that runs on dev environment and I crated the war without problems.
In the server, I stop the service using "sudo service tomcat7 stop" command and put the war file into the server folder "/var/lib/tomcat7/webapps" and start the server again with the command "sudo service tomcat7 start". For checking the state of the server I run "sudo service tomcat7 status" and get the "Tomcat servlet engine is running with pid 19169" response, and check if the application deploys correctly on the folder "/var/lib/tomcat7/webapps" and I see the project's folder there. Right now, if I check the catalina.out file, I can't see any deploy error having this:

May 27, 2020 9:04:31 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["http-bio-80"] May 27, 2020 9:04:31 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 1280 ms May 27, 2020 9:04:31 PM org.apache.catalina.core.StandardService startInternal INFO: Starting service Catalina May 27, 2020 9:04:31 PM org.apache.catalina.core.StandardEngine startInternal INFO: Starting Servlet Engine: Apache Tomcat/7.0.26 May 27, 2020 9:04:33 PM org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor /etc/tomcat7/Catalina/localhost/docs.xml May 27, 2020 9:04:33 PM org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor /etc/tomcat7/Catalina/localhost/host-manager.xml May 27, 2020 9:04:33 PM org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor /etc/tomcat7/Catalina/localhost/manager.xml May 27, 2020 9:04:33 PM org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor /etc/tomcat7/Catalina/localhost/examples.xml May 27, 2020 9:04:33 PM org.apache.catalina.startup.HostConfig deployWAR INFO: Deploying web application archive /var/lib/tomcat7/webapps/fleetcontroller.war log4j:WARN No appenders could be found for logger (net.bull.javamelody). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

But if I wait a while, the tomcat service is stoped.
When I check the server status with "sudo service tomcat7 status" I get this msg

Tomcat servlet engine is not running, but pid file exists.

And the catalina.out show me:

WARN intercept.RequestmapFilterInvocationDefinition - Exception initializing; this is ok if it's at startup and due to GORM not being initialized yet since the first web request will re-initialize. Error message is: {0} 2020-05-27 21:14:13,192 [pool-2-thread-1] WARN module.ModuleDeclarationsFactory - resources artefact KickstartResources does not define any modules | Using LESS files to generating CSS files!

Please, if someone can help with that, because I don't know how to find the problem.

Really thanks for your time.

If your tomcat dies, this most likely is something ugly (e.g. the OOM hitting). I'd dig deeper on the logs to find out was happening (e.g. also check /var/log/messages and dmesg, and if you are on systemd what the journal has to offer). - cfrick
Hi @cfrick thanks for answer. I will check that and write here what happened. The most stranger thing is that the env. is a clone of production, where all is working fine. - Martín Cabo

It was a virtual machine size problem.
I checked some server parameters and see that they was lower than production. infrastructure office changed the virtual server size and it starts to work!

Thanks you for your time!
