我怀疑内存泄漏!! [英] I suspect memory leak !!

问题描述

我们在AS中有一个Web应用程序。它还使用COM +和SQL Server作为后端。


有时dllhost.exe的大小会出乎意料地增长。这样我们就可以重新启动我们的IIS / PWS。当我们重新启动网络服务器时，只有一个dllhost运行实例

但稍后我们注意到多个实例

有时候。


请建议。

We have a web application in AS. It also uses COM+ and SQL Server as
back-end.

Sometimes the size of the dllhost.exe grows unexpectedly. It is such that we
restart our IIS/ PWS. Also there is only one instance of dllhost running
when we restart the webserver but later on we notice more than one instance
sometimes.

Please suggest.

推荐答案

你的一个COM对象正在造成它。


检查你是否在课堂上清理。即。关闭对象和数据库

连接等

并进行适当的错误捕获以避免无限循环等。


dllhost的许多实例不是真的有问题，但COM内部不整齐的代码

对象肯定会让他们咀嚼内存

one of your COM objects is causing it.

check that you clean up in your classes. ie. close objects and db
connections etc.
and do proper error trapping to avoid endless loops etc.

many instances of dllhost isn''t really a problem, but untidy code inside COM
objects will definitely cause them to munch memory

这个问题几乎肯定是由你介绍给

系统引起的。我从来没有见过dllhost.exe变得疯狂，除非在那些情况下，

是一个流氓组件，一个无限循环，未闭合的对象或一个MDAC版本

迫切需要一个升级。请查看 http://www.aspfaq.com/2227

The problem is almost certainly caused by something you introduced to the
system. I have never seen dllhost.exe go crazy except in cases where there
is a rogue component, an infinite loop, unclosed objects or an MDAC version
in desperate need of an upgrade. Please review http://www.aspfaq.com/2227

几乎可以肯定 ？


我们最近在Analysis Services中诊断出一个严重的内存泄漏，即
导致我们的DLLHOST进程最终失败。我记得在MSDN指南中使用

例外隐含地建议所有内存

问题是由于客户的设计/编程错误造成的。

"almost certainly" ?

We recently diagnosed a serious memory leak in Analysis Services that was
causing our DLLHOST processes to eventually fail. I remember taking
exception to the MSDN guidelines that implicitly suggested all memory
problems were due to design/programming errors by the customer.
