我处理我的java档案像这样。
java -Xmx8m -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xloggc:D:/MyExample/my.log MyJava
如果我的程式里有垃圾收集日志的内存泄漏 我该怎么解释呢?
请不要建议使用一个工具来阅读我的日志。 我想知道如何解释 GC 日志以确定是否有内存泄漏?
在爪哇,你可以得到的是一个不可取的记忆回缩。这不是一个螺纹意义上的记忆泄漏,但可能仍然是一个问题。
最简单的事情就是看看一个完整的 GC 后有多少内存被使用。 这可以告诉您保留内存的数量。 如果您期望保持稳定后所保留的数量会继续增加, 您就会有一个“ 渗漏 ” 。 只有您才能确定在什么时间你期望它稳定( 不大幅增加或减少) 。
