Embodiment Construction

[0034] It should be understood that figure 1 The elements shown in may be implemented in various forms of hardware, software, or a combination thereof. Preferably, these elements are implemented by a combination of hardware and software on one or more suitably programmed general-purpose devices, which may include a processor, memory and input / output interfaces. Herein, the phrase "coupled" is defined to mean connected directly or indirectly through one or more intervening components. Such intermediate components may include hardware and software based components.

[0035] This specification illustrates the principles of the disclosure. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the disclosure and are included within its spirit and scope.

[0036] All examples and conditional language cited herein are intended for instructional purposes...

Abstract

Electronic devices having limited memory resources cannot function in a reliable manner when the memory resources have ran out. In order to manage such a situation and keep the electronic device operating, a mechanism, called Out Of Memory killer, may be implemented in the electronic device. Such an OOM killer, when an out of memory situation arises, randomly selects a program running on the electronic device and terminates it. The invention consists in associating a weight to a program running on the electronic device which enables to determine which programs can be terminated because they are not considered essential and those which cannot be terminated without causing a negative impact on the quality of experience of an end-user. Lower weights are associated to programs that can be terminated, higher weights are associated to essential programs.

Description

technical field [0001] The present invention relates to a method of managing out-of-memory conditions occurring in an electronic device such as a gateway. Background technique [0002] Electronic devices with limited memory resources cannot operate in a reliable manner when the memory resources are exhausted. In order to manage such situations and maintain the operation of the electronic device, a mechanism called an Out Of Memory killer can be implemented in the electronic device. Such an OOM killer randomly selects a program running on the electronic device and terminates it when a low memory situation occurs. However, the behavior triggered by the OOM killer has unpredictable effects on electronic devices. So, sometimes OOM killer terminates programs that provide necessary functions in electronic devices. In such a case, the electronic device may no longer be operable. [0003] The present invention has been devised in consideration of the foregoing. Contents of the...
