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

Question

We have a setup for continuous integration with TeamCity and subversive activities. TeamCity gets the last source from svn and builds (Visual Studio) for each commit.

Sometimes when you build, the following TeamCity error occurs. Performing multiple power assemblies allows TeamCity to work successfully.

**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 could be happening?

Here is part of the build log

Due to an error, it looks like either the svn server was either unavailable or overloaded. In addition, if you use svn: externals that point to the same repository, I highly recommend trying TeamCity 5.1 RC - in this area there are many fixes related to support for svn + optimization. It is also recommended that you post your questions to the TeamCity forum here .
