TFS: sometimes “Object reference not set to an instance of an object” means “out of disk space”

Posted by jpluimers on 2015/09/03

A while ago, we encountered this error when doing merges in TFS (non-GIT ones):

Microsoft Visual Studio
Source Control Merge Wizard
Merge encountered 1 error(s) and 0 warning(s).
First error/warning encountered:
    Server was unable to process request. ---> Object reference not set to an instance of an object.
See output tool window for information on any other errors.
OK   Help

In the end this was caused by an out of disk space on the volume containing the TFS datastore.
