Look at CATALINA_BASE/logs/catalina.out and /var/log/messages. You may 
have to check other /var/log/* files, as each Linux distro tends to put 
certain things in other places. Might be /var/log/dmesg or 
/var/log/daemon or whatever.

Tomcat won't be shutting itself down. Something external must be
stopping the process.

Check the OS logs. This sounds like the Linux OOM killer.

Hi,

I am facing a problem regarding our application hosted in Tomcat. Our 
infrastructure is on Azure Cloud. We have hosted our application in 
Tomcat on a virtual machine deployed from Azure. After few hours of 
usage, we are experiencing that the Tomcat is going down automatically 
and we are not able to browse the application. From the memory point of 
view we have seen that when the problem is occurring then Tomcat service 
is using 1.4GB of memory. Attaching the Tomcat logs and server.xml for 
your reference. Please feel free to connect with us if you need any 
additional information. We are awaiting for your reply.


Do you have anything in the Tomcat logs about the shutdown? Or does the 
process just disappear? Have you looked at /var/log/messages to see if 
the OOME killer is killing your application?


What are the parameters you use to launch Tomcat? (Specifically, your 
heap-related parameters)?
