FIX: You receive an IPDLC link service access violation in snaipdlc!nds_rnstp_rcv_wait_reply when you configure autoactivated LU6.2 session establishment in Host Integration Server 2004 (886665)


The information in this article applies to:

  • Microsoft Host Integration Server 2004

SYMPTOMS

When you have configured Microsoft Host Integration Server 2004 for autoactivated LU6.2 session establishment, you may experience an IPDLC link service access violation in snaipdlc!nds_rnstp_rcv_wait_reply when you start Host Integration Server 2004.

CAUSE

This problem occurs when a session is requested against a certain CICS region that is currently not available. This behavior causes a LOCATE(FOUND) request not to be returned to the Host Integration Server before the LOCATE time-out expires.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

As soon as the LOCATE(FOUND) request returns, after the LOCATE time-out expires, the Advanced-Peer-to-Peer Networking (APPN) node does not match the Fully Qualified Procedure Correlation Identifier (FQPCID). Therefore, the node incorrectly assumes that the message must be a LOCATE(FIND). This behavior causes the code to incorrectly access the uninitialized Command Parameters FIND control vector that is included in the Find Resource GDS (General Data Stream) variable. Therefore, the access violation occurs in the IPDLC link service.
