最后,以下是前3个内存消耗对象的值:
000007fef9960bb0 79307 140001536 System.Byte[]
000007fef9956960 1704571 175128912 System.String
000007fef995ae68 1901299 549202440 System.Object[]
正在执行!dumpheap-mt000007fef995ae68
,我得到了一个相当长的方法表的详细信息。大多数对象的大小都相对较小,这是意料之中的。但是,在转储结束时,我看到以下内容:
00000001eb0f3220 000007fef995ae68 160

0000000237580080 000007fef995ae68 1146888
所以我继续做!gcroot 0000000 237580080
。一些初始转储如下所示:

是否仍有一个内存存在信号器的某些内存泄漏?信号器0.5.3中存在内存泄漏。我们目前的版本是1.0 alpha2,因此您可能需要更新以使用最新版本
