How To Fix XS098 - Queue for incoming messages is active

XS098 - Overview

• Message type: E = Error

• Message class: XS - SAPconnect: All messages

• Message number: 098

• Message text: Queue for incoming messages is active

What causes this issue?

Endless queues, which are not executed in normal production operation,
are contained in the SAPconnect function modules or classes for
receiving incoming message using SMTP or RFC.
Entering the OK code <NP><ZH> =DBG+ </></>in transaction SCOT activates
these queues.

System Response

All incoming messages using SAPconnect cause the program flow to hang
in one of these queues. If the queue is not exited by manual
intervention using the ABAP debugger, the ABAP process terminates with
a dump after a certain amount of time.
Automatic processing of incoming messages is not possible in these
circumstances.

How to fix this error?

Queues should be activated exclusively for error analysis by SAP.
To deactivate the queues again, enter the OK code<NP>
<ZH> =DBG- </></>.

Procedure for System Administrators
