RDS (NetEase Cloud Relational database service) has been on the line for some time, successive products have moved into the RDS, online operation and maintenance of the process, but also encountered some did not consider, or consider the incomplete things. The follow-up has time to share to everyone. Today I want to refer to a 4G RDS instance on the line, a problem with oom (out of memory), and the MySQL process was killed directly. In interpreting

Analyze Oom with MatMany oom seems to occur when bitmap is allocated, but it is generally not rootcause. The root cause is that the resources that should be freed automatically, because of code errors, cause some objects to always be referenced (Reference), such as Android memory optimizer, how to avoid mcontext references to the activity mentioned in the Oom art

Objective:C + + Programmers crave Java's freedom, and Java programmers expect the C + + constraints. Actually there is besieged, outside people want to come in, inside of people want to go out.Background:As a Java programmer, in addition to the convenience of the garbage collection mechanism, but also by the Oom (out of Memory) confusion and torture. This paper draws on Preparatory work:工欲善其事 its prerequisite, snapshot analysis of Java processes, is t

This article mainly introduces the automapper of the Oom framework, the five examples can help you solve common basic problems. Have a certain reference value, follow the small series below to see it Write in front Oom, as the name implies, object-object-mapping entities to convert each other, AutoMapper is also a cliché, its meaning is to help you do not have to manually convert simple and troublesome int

MySQL OOM series I Linux memory allocation, mysqloom RDS (Netease cloud Relational Database Service) has been launched for some time, and products have been constantly migrated to RDS. During online O M, some products have not been taken into account, or not all things. You can share it with us later. Today, I want to mention a 4G RDS instance online. The out of memory (out of memory) problem occurs, and the MySQL process is killed directly. To solve

General oom may be as follows:1, Outofmemoryerror:java heap space;2, Outofmemoryerror:permgen space;3. Outofmemoryerror:unable to create new native threadFor the 1th and 2nd cases, the JVM parameters (Xms-xmx-xx:permsize-xx:maxpermsize) can be set to adjust processing.Problem 3 occurs because we create too many threads, and the number of threads that can be created is limited, causing the exception to occur. The number of threads that can be created i

Memory Overflow (OOM): a situation in which running memory is larger than available memory. For example, the application of an integer space, the result is stored only a long to store the data memory leak (memory leak): The programmer forgot to release the memory used in the case of memory management is more common phenomenonIn the way that happens, memory leaks can be categorized into 4 categories:1. Frequent memory leaks. The code that occurs in mem

The simplest way to add content to a running constant pool is to use the String.intern () Native method. The function of this method is that if the pool already contains a string equal to this string object, a String object representing the string in the pool is returned, otherwise the string contained in this string object is added to the constant pool, and a reference to this string object is returned. Because the constant pool is allocated within the method area, we can limit the size of the

The same as the conjecture is oom. Come back to meet a little familiar SB, give me gas .... Never mind..... Brother is also a variety of reasons back to Hefei. Keep looking at the problem.

OOM killer, oomkillerIn Linux, there is an oom killer mechanism that enables selective kill of some processes when the system memory is exhausted. 1. Why OOM killer?When we use an application, we need to apply for memory, that is, to perform the malloc operation. If a non-NULL operation is returned, the application has applied for available memory. In fact, there
