You can also increase the maximum memory size but you should keep in mind that heap memory size is a portion of the total memory in a container. As I mentioned above, it needs more spaces for metadata, thread, code cache, e...
Java Web Server Tomcat S2I image. By default, the Java Web Server Tomcat S2I image calculates initial heap memory size and max memory size every time when the container spins up. However, it also provides some ways to set heap memory size. This blog shows how to decide defa...
