I am running into an issue where I am unable to shutdown the Liferay 6.2 tomcat bundle on the server via the bundled shutdown script on the new linux server.
The steps I took are:
Installed the bundle by unziping it.
Uploaded the custom portal-ext.properties in the default liferay home folder
Change the memory args as defined in the deployment best practices guide in the tomcat home/bin/setenv.sh
Added Oracle custom data source in the tomcat home/conf/context.xml
JDK - jdk1.7.0_75
Navigate to the tomcat home/bin folder -> run ./startup.sh
Liferay and the bundle comes up.
To shutdown - Navigate to the tomcat home/bin folder -> run ./shutdown.sh
This displays the following but the tomcat is not shutdown:
$ ./shutdown.sh
Using CATALINA_BASE: /.../liferay-portal-6.2-ee-sp2/tomcat-7.0.42
Using CATALINA_HOME: /.../liferay-portal-6.2-ee-sp2/tomcat-7.0.42
Using CATALINA_TMPDIR: /.../liferay-portal-6.2-ee-sp2/tomcat-7.0.42/temp
Using JRE_HOME: /.../java/jdk1.7.0_75

I see the following in the Tomcat logs.

The tomcat process is still showing after a few minutes as an active process and needs to be killed manually. Liferay seems to be down after the shutdown script is run within a minute or so.
I need this to work so all the resources are released cleanly and I can script the startup and shutdown as needed.
Has anyone seen this and resolved this behavior? Any insight would be much appreciated.
Thanks!
After working through this issue and following the steps below, the tomcat process shuts down within a minute or so with the shutdown script and there is no need to kill the process manually.
increased maxpermsize catalina_opts argument to 512m (was 200m) in the setenv.sh - this resolved 2 of the memory leak messages in the logs at shutdown and also resulted in the tomcat process shutdown properly.
removing the opensocial-portlet removed 1 memory leak error prior to the maxpermsize change but the process was still not shutdown properly.
there is 1 remaining memory leak error in the logs on shutdown but that for now is not preventing the tomcat from shutting down and seems to be part of tomcat not necessarily caused by liferay. This message for now seems safe to ignore per this LPS issue below
https://issues.liferay.com/browse/LPS-34498
Hope this helps someone.

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:

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:

Please, if someone can help with that, because I don't know how to find the problem.
Really thanks for your time.
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!
I have installed Tomcat 7 with Java 7 on a debian box. It has 512 MB of RAM. I run tomcat out of the box, I have installed nothing, and it is consistently shutting down by itself. I am not even browsing the Tomcat landing page.
As you can see, it is running perfectly normal and then all of a sudden it stops:

It just mysteriously stops. What can it be? I know the Tomcat distribution and the Java distribution are good because I downloaded them from the Tomcat site and Oracle, and FTP'd them over to my server.
There are no other errors in any other tomcat log files. Is is a permissions thing? Memory issue? Appreciate your help.
I think a memory issue would show up in the log. I would simply reinstall Tomcat and check if it's still buggy.
I am running a Tomcat Web Server(7.0) on Ubuntu. I have the same War file using Java 1.6 in my local Windows machine and I face no issues whatsoever. However, on the linux machine my tomcat fails after some time or stops working and I get Java GC exceptions. It starts with these errors :

Would Appreciate any help.
This only happens after I exit the remote shell with which I started the Tomcat Application.
does tomcat (when running with a specific user account) has access to this file, it should have enough privilege create, update & delete the file.
/home/infocomm/tomcat/work/Catalina/localhost/manager/SESSIONS.ser
in windows its very rare for this scenario to surface unless you've started tomcat as an unprivileged user.
I am taking over an existing Struts-based web application and am trying to deploy it for the first time on my local machine. My predecessor told me to run it through Eclipse on a Tomcat server.
I have installed the latest tomcat and it is running fine. I have grabbed the code from their CVS server and, with a few tweaks, removed all of the errors from the Java files. I then created a new Run Configuration having it run as "Run on server".
When I run the Run Config, the tomcat server starts up without error messages in the Console and an Eclipse browser page pops up to the correct local URL. The returned page is a 404, however. Looking at my Tomcat "webaps" folder, I see that my application is not there.
My question is, how can I troubleshoot this? My tomcat error logs do not get updated when I deploy and the Console output, shown below, offers no hint that there is a problem.

This is not the way to run web apps inside Eclipse.
Go to the Server view panel instead, and choose Add server. Here install the Tomcat adapter according to the instructions, and then add the projects you have (if they are Dynamic Web Projects). You can now start and stop the server and have the projects chosen updated when you change.
Do it this way. Do not try to create a Run Configuration launching Tomcat.
I have exactly the same problem.
While this is not a solution to the problem itself (running the project on Tomcat from within Eclipse), it is a way to run the project:
Pack(age) the project (I use maven: 'mvn clean package')
Copy the .war file into the webapps dir inside your tomcat installation.
(if not already running) Start up tomcat.
This works for me. I'm still looking for the proper answer to your question, but until I find it I'll just continue to manually package/deploy the project.
I've been running Tomcat 6 on my pc for some time now, and it has been running successfully...up until today. I just tried to start it, and now for some reason it won't start.
I start it from a command line prompt. The second prompt that appears after I enter 'startup' in the first prompt is exiting quickly, whereas it usually stays open and shows the status of the server.
Here's what the log file logged -

I never saw this before, where it says SEVERE: Null component... - what does it mean? What's causing it?
Here's what I ended up doing. I made a backup of my server.xml and web.xml files, along with my apps under the webapps folder, and removed jakarta-tomcat, and then reinstalled it. I restored the server.xml and web.xml file, threw my webapps back in, and started Tomcat up. This time, I got the same error as before, but it pinpointed that a particular servlet under one of my folders had a "bad version number". So I went through my servlet folders and recompiled the classes.
I started Tomcat again, and its running as it used to.
The problem was that a class had been compiled under a different version of the JDK, and it was causing an error.
Have you changed anything recently with regard to your Tomcat installation, configuration or deployments? Do you have a web application running under Tomcat called "MyWebApp"? If so, I would remove it and see if that fixes the problem. Otherwise, you might have to reinstall Tomcat.
