Hello,

Last night our TeamCity Server disk filled and the result has been that build sequences have been reset. Also the following error displayed when trying to view a build log of a build that ran today
Is there a way of fixing this?:

Unexpected Error

This was not supposed to happen. Please provide the error details to your TeamCity server maintainer.
If you maintain this TeamCity installation please report this error to JetBrains.
