LUA Program Hangs After Receiving Exception Request (EXR) (178256)
The information in this article applies to:
- Microsoft SNA Server 3.0
- Microsoft SNA Server 3.0 SP1
- Microsoft SNA Server 3.0 SP2
This article was previously published under Q178256 SYMPTOMS
An SNA Server LUA application may hang indefinately after receiving an
exception request (EXR) message on a session, which SNA Server sends to
the client after it has detected a bad RU in an outbound message from the
host.
CAUSE
If the host sends a bad RU on a session, the SNA Server changes the
message to Exception Request type (EXR) before sending it to the LUA
application. However, SNA Server was failing to set the End Chain (EC)
indicator on the EXR message, causing the LUA application to hang
indefinately waiting for EC to be received.
STATUS
Microsoft has confirmed this to be a problem in SNA Server 3.0 (including
SP1 and SP2).
This problem was corrected in the latest SNA Server version 3.0 U.S.
Service Pack. For information on obtaining this Service Pack, query on
