SYMPTOMS
========
When you run a CPIC application on Windows 95, the CPIC application stops
responding intermittently when you try to acquire the conversation. Traces show
that the CM_Init request is not getting a response.
CAUSE
=====
This problem occurs if both of the following conditions are true:
- The CPIC application calls WinCPICCleanup() while there are pending RPC
requests.
-and-
- The RPC response arrives before SNAKRNL has closed all connections.
The following is a call to WinAPPCCleanup. Under the covers, there are still
outstanding rpc requests:
APPC WinAPPCCleanup response, result = TRUE
CPIC ---------------------------------------------- 09:34:42.49
CPIC WinCPICCleanup response, result = TRUE
CPIC ---------------------------------------------- 09:34:42.99
CPIC WinCPICStartup request
CPIC
CPIC Version Requested = 1.0
APPC ---------------------------------------------- 09:34:42.99
APPC WinAPPCStartup request
APPC
APPC Version Requested = 1.0
APPC ---------------------------------------------- 09:34:42.99
APPC WinAPPCStartup response, result = OK
APPC
APPC Version Supported = 1.0
CPIC ---------------------------------------------- 09:34:42.99
CPIC WinCPICStartup response, result = OK
CPIC
CPIC Version Supported = 1.0
The following is a request to start the conversation. There is no return to the
CMNIT() CPIC call:
CPIC ---------------------------------------------- 09:34:43.10
CPIC CMINIT request
CPIC Sym dest name = QR27
APPC ---------------------------------------------- 09:34:43.10
APPC TP_STARTED request
