This afternoon we started seeing the following errors across all build configurations on one of our TC build servers:
Failed for the root 'Git' #46: The repository at directory 'C:\ProgramData\JetBrains\TeamCity\system\caches\git\git-1A7BA372.git' cannot be opened or created, reason: null
Another server with identical build configurations (and using the same Github repos) is fine, no issues whatsoever.
Any ideas on what is wrong (and more importantly, how to fix it?)?
