为什么我会得到；svn:服务器拒绝了连接；？

我们有一个与TeamCity和subversion的持续集成环境。团队城市 从svn获取最新的源代码，并在每次提交时执行生成（Visual Studio）

有时，当构建运行时，我们会出现以下TeamCity错误。进行两次部队建设可以使TeamCity成功运行

**Build errors
[12:35:24]: Patch is broken, can be found in file: C:\TeamCity\buildAgent\temp\cache\temp6036patch_803[12:35:24]: RunBuildException when running build stage UpdateSourcesFromServer: Failed to build patch for build 519 {build id=803}, VCS root: svn: https://svn.myDomain.com/repos/myApplication {id=2}, due to error: org.tmatesoft.svn.core.SVNException: svn: connection refused by the server
svn: REPORT request failed on '/repos/myApplication/!svn/vcc/default'**

你知道为什么会这样吗

这是构建日志的一部分

从错误中可以看出，svn服务器不可用或过载。 此外，如果您使用的是指向同一存储库的svn:externals，我强烈建议您尝试TeamCity 5.1 RC-在这方面有许多与svn支持+优化相关的修复程序。

另外，最好将您的问题发布到TeamCity论坛。

您是否可以访问apaches错误日志（并可以在此处添加错误日志）？服务器故障有一个关于的规范问题。
