MessagingException: Sequence already terminated (soft).

Hi,

I'm getting the following error after the execution of an IDoc>SQL interface.

The queue shows "XI Error ERROR_OBJECT.INTERNAL: Queue stopped" in FM SXMS_ASYNC_EXEC.

The message with error, in SXMB_MONI, says:

<SAP:AdditionalText>com.sap.engine.interfaces.messaging.api.exception.MessagingException: 
Sequence already terminated (soft).</SAP:AdditionalText> 

Does anyone ever faced this error?

Tks.

Rafael.
