Symptom

WebSphere MQ First Failure Symptom Report
=========================================  
Probe Id          :- AT041015
Component         :- atxStart
Major Errorcode   :- arcE_XAER_PROTO
Minor Errorcode   :- OK
Probe Type        :- INCORROUT
Probe Description :- AMQ6125: An internal WebSphere MQ             error has occurred.
FDCSequenceNumber :- 0


Diagnosing the problem

The FDC indicates that an application requested a new eXtended Architecture (XA) transaction be started, while one is already active for the thread, that is. an xa_start is being requested before an xa_end has been performed in the same thread or process. This is not a valid request and should return an error to the application that issued the xa_start.

Resolving the problem

Investigation should be done in the XA code at the Transaction Manager (TM) level outside of WebSphere MQ to determine where and why the xa_start is being issued inappropriately.
