Errors during build execution while downloading large files from Version Control

August 3, 2011

In a large SharePoint development project at a customer I was confronted with the not always reproducible build error while syncing the build workspace:

Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host


This error sometimes occurred while downloading the larger database backup files (> 1.5GB) which are required in the deployment and test phase.

Luckily a patch (KB981898) for the TFS Application Tier (Windows Server 2008 R2) does exist to resolve this particular issue! Also have a look at this blog article for more background info.

Also thanks to Giulio Vian for helping me out with this issue!
