When attempting to take actions that trigger Symantec Protection for SharePoint Services (SPSS) scans within Sharepoint 2010, and system load is heavy, items cannot be be accessed as long as SPSS scanning is enabled.
In the application event log of the Sharepoint server, multiple Event ID 0s from Source "Symantec Protection for SharePoint Services" with the following details are logged:
Module=ScanObject.Scan | Exception message=Failed to connect to an IPC Port: The system cannot find the file specified.
| Stack=

Cause
A defect in the underlying version of .NET framework causes Inter-Process communication (IPC) channel exhaustion during the heaviest load periods in the Sharepoint farm.
