Exception Handling series: java. lang. OutOfMemoryError: PermGen space, permgen Today, I helped my colleagues solve the problem of Tomcat startup and reported an OutOfMemoryError. Then I searched and found it very interesting. The solution is as follows: The memory is full. So we need to increase the Tomcat memory pool a little. Modify as follows:1. window --> Preferences, and then write "tomcat" directly

Seeing this pile of information, I think you should know what to do. Main at java.lang.outofmemoryerror. Increased memory, increased memory, memory overflow, so I set the java_opts=-server-xms2048m-xmx2048m-xx:permsize=1024m-xx:maxpermsize=512m-xss512k Reboot the server, not too long and outofmemoryerror It's time to know the damn outofmemoryerror, So, please add to java_opts -x

greater than the maximum allowed depth for the virtual machine .Throws a OutOfMemoryError exception if the virtual machine cannot request enough memory space on the scale stack .Here the exception is divided into two situations, seemingly more rigorous, but there are some overlapping places: when the stack space can not continue to allocate, whether the memory is too small, or has been used in the stack space is too large, it is essentially only two

There are 3 types of memory in the JVM: Heap (heap memory), Non-heap (non-heap memory) [3], and native (local memory). [1]Heap memory is an area of memory where all class instances and arrays are allocated at run time. Non-heap memory contains the memory required to process or optimize the method area and the JVM, storing class structures such as run-time pools, fields and method structures, and methods and constructor code. Local memory is virtual memory managed by the operating system.An java.

1, StackOverflow:Whenever a Java program launches a new thread, the Java virtual Opportunity allocates a stack for him, and the Java stack keeps the thread running in frames, and when the thread calls a method, the JVM presses a new stack frame into the thread's stack, and the stack frame exists as long as the method does not return.If a method has too many nested call hierarchies (such as recursive calls), as the number of frames in the Java stack increases, the sum of all the stack frames in t

In the JVM memory area, the OutOfMemoryError (OOM) exception may occur in several other run-time zones in addition to the program counters. This article sums up the oom exception, verifies the contents of the runtime zone as described in the JVM specification by code, and understands the code that might cause these areas to oom exceptions, and can locate the memory area in the work based on the exception code. Based on the Sun's hotspot virtual machin

OutOfMemoryError in the development process is commonplace, encountered this error, novice programmers know from two aspects to solve:1: is a bug that causes a memory leak;2: is to adjust the JVM startup parameters to increase memory.OutOfMemoryError There are several cases, each time you encounter this error, observe the outofmemoryerror behind the message, you can find the difference, such as:ReferencesJa
