The information in this article applies to:

Microsoft SNA Server for Windows NT, versions 2.0, 2.1, 2.11, 2.11 SP1, 3.0

SYMPTOMS

If the NVAlert service encounters data for a configured event that exceeds 4 KB in size, the NVAlert service may stop responding. The following event is logged when this problem occurs:

   Event ID: 3006
   Source:   SNA Netview Alerter
   Type: error
   Description : Error reading log event record.Handle specified is
    <handle>.
   Return Code from ReadEventLog is 122.

CAUSE

The NVAlert service is not properly allocating memory large enough to handle an alert that exceeds 4 KB.

RESOLUTION

The NVALERT code has been modified to allow any size Event Log entry. If the current buffer size is not large enough, it is increased to accommodate the size.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 2.0, 2.1, 2.11, 2.11 SP1, and 3.0. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
