已发生多次Web服务错误 [英] Web Service error that has occurred several times

问题描述

在多台机器（有Asp.net 1和2）我们已经看到下面的错误与随机文件名（以的.dll 扩展）每次产生我们试图让Web服务调用。

在过去，我们不得不重新安装 asp.net 这似乎已经固定它。

但是，有一次，我们试图让命令提示符窗口，并用约低资源错误回来。重新启动服务器似乎已经修复了这个问题。

任何想法是什么原因造成这个错误？

以下错误：

  System.Web.Services.Protocols.SoapException：服务器无法处理请求。 ---＆GT; System.IO.FileNotFoundException：未能找到文件'C：\\ WINDOWS \\ TEMP \\ aweww1ss.dll。

解决方案

如果重启解决，这意味着你的机器基本上都是跑出来的临时文件存储空间的问题，常规的前pressions和很多工具，包括动态编译（ASPX等），产生大量的临时文件，并重新启动服务器或清洁的临时文件应该可以解决问题。

.NET应用程序是有点不好，为运行很长时间，我们有服务器的问题时，我们并没有重新启动他们的天......那么作为天通经，日志，内​​存碎片整理等的推移越来​​越大，我想有时减缓都记录下来。 .NET应用程序通常不去除他们打开，资源上的锁它不是开发商的过错，而是.NET垃圾收集的心不是，如果文件关闭的werent或删除聪明，所以你的临时文件可能增长。

最好是做定期软重启喜欢每周一次在周日晚上等将有助于管理.NET应用程序很好。

On a number of machines (with Asp.net 1 and 2) we have seen the below error with a random file name (with .dll extension) produced each time we try to make the web service call.

In the past we have had to reinstall asp.net and that seems to have fixed it.

However, on one occasion we tried to get the command prompt and windows came back with a error about low resources. Rebooting the server seemed to have fixed this issue.

Any ideas what is causing this error?

解决方案

If rebooting solved the issue that means your machine basically ran out of temp file storage space, your regular expressions and lot of tools that involve dynamic compilation (aspx etc), creates lot of temp files, and rebooting server or cleaning temp file should solve issue.

.NET apps are little bad to run for long time, we had server issues when we were not restarting them for days... then as days pass by, the logs, the memory defragmentation etc goes bigger and bigger and i think that sometimes slows everything down. .NET apps usually dont remove locks on resources they opened, its not developer's fault but .net garbage collection isnt that smart, so your temp files may grow if files werent closed and deleted.

Best is to do soft reboot on regular intervals like once a week on sunday night etc will help managing .net apps well.
