Resolved Caveats—Cisco IOS Release 12.0(7)

IBM Connectivity

• CSCdm37638

A Cisco 4500 or 4700 series router with an NP-2R Token Ring might pause indefinitely

approximately once a week and display the following error message:

%SYS-2-INPUTQ: INPUTQ set, but no IDB

This condition is not effected by the revision level of the motherboard. There is no workaround.

• CSCdm51285

A Cisco router might reload with a Segv exception error with the following stack trace:

System was restarted by error - a SegV exception, PC

0x8084D788[k_convSdllcPortEntry_get(0x8084d67c)+0x10c] k_convSdllcPortEntry_get

convSdllcPortEntry_get GetNextObjectInstance do_response do_snmpv1 do_mgmt snmp_engine

ip_snmp

Workaround: Delete the entry in the ASN.1 private Cisco MIB that is causing the router to reload.

• CSCdm55118

A Cisco router using Advanced Peer-to-Peer Networking (APPN) may consume excessive CPU

resources while issuing messages during a locate storm. The “XXXTPD02_LOGMSG_01”

message might appear repeatedly. There is no workaround.

• CSCdm59024

A data-link connection might not recover when the Advanced Peer-to-Peer Networking (APPN)

link is not restarted, although the router is configured to retry repeatedly. This situation occurs

when a Cisco 4700 router is defined as an APPN network node with an APPN link across Frame

Relay RFC 1490 to an IBN NN950 that is configured as a network node. There is no workaround.

• CSCdm64065

No SNA traffic passes between a server and a Cisco Network Node router when the network node

uses DLSw flow control to disallow the sending of further SNA traffic by the server. There is no

workaround.

• CSCdm67191

A Dependent logical unit Requester physical unit (DLUR-PU) might appear stuck in a “stopping”

state while waiting for a deactivate physical unit (DACTPU) request from a Dependent logical unit

server (DLUS). In this situation, the DLUS has already cleaned up this PU, and the PU is in a

connectable state on virtual telecommunications access method (VTAM). The DLUR cannot clean

up this PU until it receives the DACTPU request. This software change allows DLUR-PUs that have

waited for this DACTPU for more than 2 minutes to issue another REQDACTPU request to the

DLUS. If the DLUS has already cleaned this PU, it will respond negatively to the REQDACTPU.

This negative response will initiate the cleanup of this PU by the DLUR. There is no workaround.

• CSCdm71190

An Advanced Peer-to-Peer Networking (APPN) network node router might not allocate the

conwinner session of its dual control point-to-control point session with an adjacent end node. The

conloser session is set up correctly, but the conwinner session fails in sense 0x80140003 if you

issue the debug appn ss command.

Workaround: This situation results if you change an adjacent network node to an end node. Cycle

the link for the end node that you changed.
