We are running TeamCity 5.0.1 and have just migrated from 4.5.5. When we start up TeamCity and hit the servlet we are now seeing:
jetbrains.buildServer.rootDispatcher.SecondTeamCityInstanceException: Attempted to start more than one TeamCity servers connected with one database.
This database was previously used in TeamCity 4.5.5 and was working for a few minutes (before we rebooted the OS -- Linux). We created an empty database which does work, but we'd really like to keep the old data!
We are really sure that only one instance of TeamCity is running against this database (a MySQL database). Is there some lock file or table that we can clear?
