This article was previously published under Q182269 SYMPTOMS
Under certain timing conditions, the SNA Server TN3270 service may log the
following event:
Event ID: 902
Source: TN3270 Server
Description: Logic error in module TCPRecv identified by:
IOAlreadyOutstanding
EXPLANATION
An unexpected logic error has occurred.
ACTION
Record message and contact technical support.
However, this does not cause any TN3270 client connectivity problems. This
event has been reproduced when the Wall Data Rumba TN3270 client is
connected through the SNA Server TN3270 service configured to use an SNA
Server 3270 demo link service or to an actual host application.
CAUSE
In certain timing conditions, the TN3270 service was posting a second
TCP/IP receive request against a socket, while a previous receive command
was already outstanding. This is a benign condition and should not be
logged.
STATUS
Microsoft has confirmed this to be a problem in SNA Server version 3.0, 3.0 SP1, 3.0 SP2 and 4.0. This problem was corrected in the latest SNA Server version 3.0 and 4.0 U.S. Service Packs. For information on obtaining these Service Packs, query on the following word in the Microsoft Knowledge Base (without the spaces):
MORE INFORMATION
With this update applied, the TN3270 service no longer logs this specific
error condition.
