Two methods are used in total. One is the local method that throws an exception according to the log printed by the system during the VM crash to find out which function is finally called.
Tomcat itself cannot run directly on a computer. It depends on an operating system based on hardware and a Java virtual machine. When the Java program starts, the JVM allocates an initial memory and the maximum memory to the application. The initial memory and maximum memory will affect the performance of the program to a certain extent. For example, when applications use the maximum memory, the JVM needs to first perform garbage collection to release some occupied memory. Therefore, to adjust t
