TFS error - TF400898: An Internal Error Occurred

Question

Okay, nothing had changed in TFS (at least to my knowledge and I'm the administrator!).

I received the error "TF400898: An Internal Error Occurred", when clicking on a previous sprint in the backlog. A colleague also received the same error when trying to move an item within an iteration of the current backlog.

Navigating to each team, opening the 'Configure work areas...' menu and doing nothing more, appeared to correct the error (or was it a coincidence?).

Has anyone got a clear and definitive answer as to why the error occurred? More importantly, how to correct it? Surely there's more to my simply browsing between the teams.

Solution 1

This error can also arise, if the TFS server is out of disk space.

Solution 2

It's hard to give a clear and definitive answer, as the error is not able to be reproduced on others/my environment.

But there are some tips for you to troubleshoot this issue:

1. Make sure your TFS2012 has upgraded to latest edition.

2. Check this blog to see whether you have provisioning logic issue.

3. Clean the Cache folder on Server machine. The folder path is: C:\ProgramData\Microsoft\Team Foundation\Web Access\Cache_v11.0

4. Check Event Log in Event Viewer to see whether there is useful information.
