This article was previously published under Q183552 SYMPTOMS
When you are accessing a mainframe file, if the LU6.2 connection is
terminated abruptly, the SNA DDM service terminates with an unhandled
exception. Bad data can be written to the mainframe file; also, when the
OLE DB Provider reads bad data from the mainframe, it crashes.
CAUSE
The mainframe deallocates the LU6.2 conversation with CONV_FAIL_ABEND. The
OLE DB Provider, regardless, tries to interpret as application data the
LU6.2 information returned from the mainframe. This results in an access
violation.
STATUS
Microsoft has confirmed this to be a problem in Microsoft OLE DB Provider
for AS/400 and VSAM version 1.00, included with SNA Server version 4.0.
This problem was corrected in the latest SNA Server version 4.0 U.S.
