What is the memory management mechanism in Tomcat?

The memory management mechanism in Tomcat is primarily controlled through the Java Virtual Machine (JVM). Tomcat is a Java-based web application server that operates on the JVM, thus inheriting Java’s memory management system.

In Tomcat, JVM automatically handles memory allocation and release, managing both heap memory for storing object instances and arrays, and stack memory for storing method calls and local variables.

The JVM also performs garbage collection on memory, automatically releasing unused memory space to prevent memory leaks and overflow issues.

In addition to managing memory, Tomcat can also control memory allocation and usage through configuring JVM parameters, such as setting heap size, stack size, garbage collection policies, etc.

In general, the memory management mechanism in Tomcat is based on the automatic memory management mechanism of the Java Virtual Machine, which uses the JVM to manage memory allocation, deallocation, and recovery.
