During the creation of a Site Collection in Microsoft SharePoint 2010, custom solutions can be activated (WSP files, e.g. from a Solution Gallery in SharePoint).
With these solutions activated, custom templates become available to be loaded. Loading the (custom) templates results in an error “An unexpected error has occurred”. The status shows “Site creation failed”.
Errors also appear when scan on upload in SPSS is disabled, and Scan engine does not show any errors.
No errors appear when SPSS is not installed.
An unexpected error has occurred
Troubleshoot issues with Microsoft SharePoint Foundation
During the activation of the solution, SharePoint calls the AV scanner. Whenever AV scanner calls our SPSS component it acquires a TCP channel however the same channel is also required by the activation process of the solution.
This is causing a TCP Channel conflict between SPSS and SharePoint.
