Such as:

Repeatedly, the problem remains unresolved, including restarting the Linux system with the reboot command.

But strangely, after more than 10 minutes, respectively run shutdown.sh and startup.sh again, found that the above problems have not appeared, Tomcat resumed normal, do not know what is going on.

After a number of such problems, and then finally found that Tomcat is too small memory, need to add virtual memory to Tomcat, increase the memory of Tomcat, the problem is resolved, and finally can shut down or start tomcat again. Click here to view: How to modify Tomcat memory in a Linux system.
