Fatal Exception Errors in Wsipx.vxd (192445)

SYMPTOMS

When you run a program that uses Windows sockets over the IPX/SPX protocol to transfer large quantities of datagrams, you may receive either of the following error messages:

- An exception 0E has occurred at 0028:C1029F6C in VxD
WSIPX(01) +00000DBC.
This was called from 0028:C0043174 in VxD NDIS(01) +00000D7C

- A fatal exception has occurred at 0028:C10297D1 in VxD
WSIPX(01)+00000621.
The current application will be terminated.

Also, your computer may stop responding (hang), or the client process on the remote computer may report transmission errors. Note that this problem is more likely to occur with slower computers.

CAUSE

This problem can occur if a buffer being used by a Windows sockets program is inadvertently freed twice by Windows Network Sockets for IPX (WSIPX) and the IPX/SPX-compatible protocol (NWLINK) then tries to access this buffer.

RESOLUTION

This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows.
