Our 8.1.3 build of TeamCity has been stable and untouched since upgrading a few months back.
It has started to play up now and the only way to get it working again is to restart the TC Windows Service.
The exact error is:
Failed for the root 'svn://server.xxxx.co.uk/mysvnpath' #10: svn: E210003: connection refused by the server
Connections from this server to SVN using the same account (at the same time as the error) still work via TortoiseSVN.
Restarting TC service gets it to run successfully once more, then it fails again.
I've recreated the VCS root to no avail.
It seems as if something is left in an odd state by the service and not cleaned up after the initial connection, my guess is an open socket to SVN.
Can anyone point me in the right direction? Server is Windows 2012, TC installed as an agent. Other projects carry on working (to different repos).
