Cause

This problem may occur if the server hosting the ASP.Net application has been configured with the /3GB switch enabled.

Resolution

To resolve this problem, remove the /3GB switch from the c:/boot.ini file. For information on locating and editing the boot.ini file, please see the following article:

More Information

By default in 32bit Windows operating systems, Windows uses a virtual address space of 4 GB, with 2 GB allocated to user-mode processes (for example, applications) and 2 GB allocated to kernel-mode processes (for example, the operating system and kernel-mode drivers). On systems that have 1 GB or more of physical memory, the /3GB switch can be used to allocate more memory to applications (3 GB) and less memory to the kernel (1 GB). 

When you use the aspnet_state.exe in ASP.NET to store session, the ASP.NET Web server process (w3wp.exe) communicates with the state server(aspnet_state.exe) by using WinSocket over Transmission Control Protocol/Internet Protocol (TCP/IP). When storing large amounts of data in session, it is possible for the worker process to not be able to buffer session data properly at the TCP/IP level due to the reduced kernel mode memory space caused by the /3GB switch being enabled, and the above error messages can occur.
