我知道有没有简单的回答我的问题，但我会AP preciate思想，指导或 某种东西到查找在列表

I know there is no simple answer to my question but I would appreciate ideas, guides or some sort of things-to-look-at list

我有一个网络的Windows服务，不断抛出OutOfMemoryException异常。 该服务有两个版本的x86和x64的Windows。然而在x64它消耗了很多 记忆。我曾尝试与不同的内存分析器分析它。但我不能得到一个线索是什么问题。诊断 - 服务消费VMSize的很多，崩溃后3〜12小时的应用程序。该behaviuor是相当随机的 - 没有任何可观察到的图案碰撞场景

I have a net Windows service that is constantly throwing OutOfMemoryException. The service has two builds for x86 and x64 Windows. However on x64 it consumes a lot more memory. I have tried profiling it with various memory profilers. But I cannot get a clue what the problem is. The diagnosis - service consumes lot of VMSize and crashes app after 3 to 12 hours. The behaviuor is rather stochastic - there is no observable pattern for crash scenario.

我也想看看性能计数器（PERFMON.EXE）。我可以看到的是， 堆大小的增长和GC％的时间平均为19％。加上内存分配与相关％的CPU时间。

Also I tried to look at performance counters (perfmon.exe). What I can see is that heap size is growing and %GC time is on average 19%. Plus memory allocation is correlated with %CPU time.

我的应用程序的线程和锁定的对象，数据库连接和WCF接口。 我试图解决一般问题：

My application has threads and locking objects, DB connections and WCF interface. The general question that I am trying to solve:

这纯粹是没有GC速度不够快   对GC的物体或一些非管理   （视窗）对象被消耗   内存？

Is it simply GC not been fast enough to GC objects or some non-managed (windows) objects are consuming memory?

请参阅列表中的第一个应用程序

推荐答案

是你的问题，你不知道什么是占用了大量的内存？您可以打开，当进程正在使用大量内存的任务管理器，右击你的过程，并创建可在WinDbg中检查找出到底什么是分配内存转储文件。

Is your issue that you don't know what is consuming a lot of memory? You can open up task manager when the process is using a lot of memory, right click your process and create a dump file which you can examine in windbg to find out exactly what's allocating memory.
