SYMPTOMS
In SNA Server, an Access Violation (AV) occurs after logging Event 3. If this problem occurs, the SNA Server service terminates unexpectedly. The following events may be logged in the application event log at the time of the failure:
Event ID: 3
Source: SNA Server
Description: (1106) Node Configuration Error
NOTE: Subcode X'1106' indicates that the configuration file (Com.cfg) is corrupted.
Event ID: 624
Source: SNA Server
Description: Creating dump file [path]\snadump.log for snaserver.exe
If Drwtsn32.exe is configured as the default debugger on the SNA Server system, the Drwtsn32.log will be updated with the Access Violation information for Snaservr.exe.
In the reported instance of this problem, the SNA Server was also logging the following event prior to the Access Violation:
Event ID: 22
Source: SNA Server
Description: APPC session activation failure: BIND negotiated parameters unacceptable
CAUSE
Under certain circumstances, the SNA Server service (node) can delete an Advanced Program-to-Program Communications (APPC) mode record and its associated mode data record from its internal configuration structures even when the mode data record is still being used by another mode record. This causes the configuration to become corrupt, which will lead to the problem described here.
RESOLUTION

This problem was first corrected in SNA Server 4.0 Service Pack 4.
