This is my impression of Eclipse, because I have a memory shortage of M hosts. Please use the-vmargs-xmx adjustment prompt. Then, I can only close eclipse, otherwise it will be left empty. At ordinary times, my brain uses habitual Filtering for such prompts, but today I can't help it. I want to see how it works and how it can be better to write code.This is the resource I found online: Java Virtual Machine

Problem Description: Start SoapUI-5.0.0 times error, which causes the program to fail to start: The JVM could not being started. The maximum heap size (-XMX) might is too large or an antivirus or firewall tool could block the execution. Problem Analysis: From this error, it can be determined that the boot parameter (-XMX) configuration is too large to exceed the system's maximum available resources

"Could not create the Java Virtual machine" encountered a problem while running Java programs. As follows:The reason is that the Java heap is running out of memory to run the JVM and requires additional memory.Searching for this problem on the Internet is mostly a workaround for a program that modifies the JVM's memory, such as Eclipse, and so on. What if there a

. OutOfMemoryError: PermGen space JVM manages two types of memory, heap and non-heap. Heap is used by developers. It is created at JVM startup. Non-heap is reserved for JVM and used to store class information. Unlike the heap, GC does not release space during runtime. If the web app uses a large number of third-party jar files or the application has too many class files, but the MaxPermSize setting is small, exceeding this will also cause excessive memory usage and overflow, or during hot deploy

GC (garbage Collection) should not clean up the PermGen space, so if your app will load a lot of class, it's likely that PermGen space error will occur Java Heap is divided into 3 districts 1.Young 2.Old 3.Permanent Young saves a newly instantiated object. When the area is filled, the GC moves the object to the old area. The permanent area is responsible for saving reflection objects. The heap allocation of the JVM can be set u

. Its default space (that is,-XMS) is 1/64 of physical memory, and the maximum space (-XMX) is 1/4 of physical memory. If the memory is less than 40%,JVM the value of the heap to the XMX setting is increased, the memory remaining more than 70%,JVM will reduce the heap to XMS setting value. So the server's xmx and XMS settings should generally be set identically t
