从大约一年(也许更多)开始，我不断有进程被 linux oom-killer 杀死。运行的机器是我的 htpc 使用 ubuntu gnome 15.04(当前)。
每天一次或有时连续 10 次被杀死的两个进程要么是 KODI(正式名称为 XBMC 广告)要么是我的 jdownloader 通常在后台闲置。
机器有 8GB 内存但没有交换空间(从来没有)。除了硬件更改和每年一次的操作系统升级之外，这是我多年来的设置。我不能确定这个问题是什么时候开始的，但大约一年后我看到 jdownloader 或 kodi 被 oom killer 随机杀死。我尝试了一些内存日志记录，发现我的 8GB 内存的内存使用率从未超过 35%。
在网上查看各种类似的问题对我没有帮助，尽管可能是因为我对这个主题了解不多。
我在使用相同的软件时从未遇到过此类问题，但在我的旧 4GB ram htpc 上使用较旧的 ubuntu。我以为 jdownloader2 可能有内存泄漏，但我在网上没有发现任何关于它的信息，也没有观察到任何进程使用超过百分之几的 ram。
我什至切换到不同的内核(目前是主线 4.0.5)，但没有任何帮助。
无论如何，也许有人可以告诉我实际问题是什么。这里有一些杀戮日志:
