The information in this article applies to:
- Microsoft SNA Server, versions 3.0SP3, 4.0, 4.0SP1, 4.0SP2
-------------------------------------------------------------------------------
SYMPTOMS
========
When using persistent verification on LU6.2 sessions, SNA Server may fail
unexpectedly with the following event:
Event ID: 686
Source: SNA Server
Description: SNA Server Internal buffer pool error
When this occurs, all SNA Server processes must be restarted, including SnaBase
and the SNA Server service.
CAUSE
=====
To support persistent verification, the SNA Server service may be required to
remove the password vector from the FMH-5 Attach request received from the SNA
Server APPC DLL (Wappc32.dll). In one case, SNA Server failed to properly
reformat the message, which resulted in internal SNA buffer pool corruption.

==========
