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
