Why am I getting "svn: connection refused by the server"?

Question

We have a Continuous Integration environment setup with TeamCity and subversion. TeamCity gets the latest source from svn and does a build (Visual Studio) on every commit.

Sometimes we get the following TeamCity error when the build runs. Doing a couple of force builds gets TeamCity running succesfully.

**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'**

Any ideas why this might be happening ?

Here is part of the build log

From the error, it looks like that either svn server was either unavailable or overloaded. Also, if you're using svn:externals which point to the same repository, I strongly suggest trying TeamCity 5.1 RC - there were a bunch of fixes related to svn support + optimization in this area. Also, it is a good idea to post your questions to TeamCity forum here.
