dropbox oom

Android Oom sometimes appears very often, which is generally not a problem with Android design, which is generally our problem.As far as my experience is concerned, the occurrence of oom is mainly the following:One, the loading object is too largeSecond, the corresponding resources too much, not too late to release.To solve this problem, there are several aspects:One: To do some processing on memory referen

Load large images efficientlyWe often use a lot of pictures when we write the Android program, different pictures will always have different shapes, different sizes, but in most cases, these images will be larger than the size of our program. For example, the pictures in the system pictures are mostly taken from the mobile phone camera, the resolution of these images is much higher than the resolution of our phone screen. As you should know, we write applications that have a certain memory limit

Recently often received MySQL instances similar to the lack of memory alarm information, landing to the server on a look found that MySQL ate 99% of memory, God! Sometimes the kernel will help us restart MySQL on its own, and then we can see that the DMESG information has the following records: Mar 9 11:29:16 xxxxxx kernel:mysqld invoked oom-killer:gfp_mask=0x201da, order=0, oom_adj=0, oom_score_adj=0Mar 9 11:29:16 xxxxxx kernel:mysqld cpuset=/mems_

Mysql backup Big Table problem-mysqldump missing-q Parameter causes MySQL to be killed by oom? One day early morning, I received a db Fault Warning and went to the machine for check. mysql was restarted by the myqld daemon. Check varlogmessages and the recent dmesg and find that the mysql process is killed by oom. The following is an excerpt from the information :? [13045702.638964] kthreadi Mysql backup Bi

Usually there are two conditions for OOM: 1. no more pages can be allocated in the VM (note that linuxkernel delays page allocation policies and alloc only when used; therefore, malloc + memset is valid ). 2. insufficient user address space. in this case, 32-bit machines and userspace exceed 3 GB, which is unlikely to happen on 64-bit machines. There are generally two conditions for OOM: 1. no more pages ca

thread. Serial GC is suitable for small applications and single-Processor Systems (with high efficiency without multi-thread interaction). The latter two are suitable for large systems. You can add-XX: + useparallelgc to the parameter configuration. There are a lot of examples for this part of configuration on the Internet for reference, but the final GC should be analyzed and selected based on the specific situation. Heap: The Experiences of OOM hav

In the previous blog post on Android bitmap memory restrictions, we learned in detail and analyzed why AndroidThe OOM error occurs when bitmap is used. In short, Android uses local code to complete decoding during image decoding, but the memory used is the memory in the heap, the heap memory size is limited by the available memory size of the VM instance. Therefore, when the available memory of the application cannot meet the decoding needs, Android w

Inside June recently to Mr. Jin Yong's laugh and proud of the river to see three times, feeling a lot. A lot of work, management, life, learning problems can be in a glimpse of it, and that is a young can not experience a feeling. such as the following wind of this passage: The wind said: "In the martial arts alone, these demons and the elders can not say that the real door of the study of Kung Fu." They do not know that the trick is dead, and the people who send the recruit is alive. Death tri

Many may be familiar with the OOM (OutOfMemory) error. How can this problem be effectively solved? Today, let's talk about how to use soft references and weak references to effectively solve the OOM problem in the program. The following is the directory outline of this article: 1. understand the concepts of strong references, soft references, weak references, and virtual references. further understanding of

IntroductionIn Android, we usually use Android's messaging mechanism to communicate between threads, and this mechanism passes exactly the message.Usually. We use Message.obtain () and Handler.obtainmessage () to get a message from the message pool. Avoid constructing a message directly. So does Android cause oom because of the message pool cache message object? For this question, I can understand that app*** will not be

Scenario Description: In practical applications, when an oom anomaly occurs, it's not what we expect. We force the process to terminate, in fact, to shut down the service, causing the service to fail, to some extent, the system crashes or restarts or freezes, there is no difference. For the actual customer, the inability to provide the service itself is an exception, whether for the need of downtime or the cooling of the machine. In fact, we should al

OOM is short for Android out of memory. When developing apps Based on Android, out of memory may often appear.Exception.In Android, a process can only use 16 MB of memory. If this limit is exceeded, this exception occurs. This requires us to always think about releasing resources. Java Collection is handed over to GC. There are many ways to enable GC to recycle unused objects in real time. OOM is very simpl

1. OOM Introduction Object-OrientedModel (OOM) object-oriented model. An OOM contains a series of packages, classes, interfaces, and their relationships. These objects form a class structure of all (or part) the logic of a software system design view. An OOM is essentially a static conceptual model of a software system

In the Java virtual machine specification, there are two exceptions to this area of the virtual machine stack :(1) If the thread requests a stack depth greater than the virtual machine allows, the STACKOVERFLOWERROR exception will be thrown;(2) If the virtual machine stack can be dynamically extended (most of the current Java Virtual machine can be dynamically extended, but the Java Virtual Machine specification also allows a fixed-length virtual machine stack), when the extension cannot request

This example summarizes the memory overflow solution for Android programming (OOM). Share to everyone for your reference, specific as follows: Oom problems often occur when you see too many pictures loaded or when pictures are too large in a recent project. Looking for information on the Internet also provides a lot of methods, but I feel a bit messy, hereby, today in different models of three Android mobi
