DB2 FOR LUW / DB2FORLUW / B10 - DB2

We have a query calling MON_GET_PKG_CACHE_STMT  (with the member
parameter set to "-2" so that request is sent to all nodes).
Moreover, that query also specifies "FETCH FIRST 1 ROWS ONLY" so
that the query is satisfied when 1 row is returned.   Since "-2"
was specified the MON_GET_PKG_CACHE_STMT request is sent to all
nodes.   The local node returns its data and the table function
closes due to the "FETCH FIRST 1 ROWS ONLY".  In addition the
app issuing this query immediately terminates; this termination
results in a "STOP USING" interrupt being sent to all nodes.
On a remote node by the time the app is initialized and the
MON_GET request is passed to a subagent the STOP USING interrupt
has arrived.   The arrival of that interrupt is detected and the
probes are written out and the MON_GET request is aborted.
This is highly timing sensitive; it only occurs if the STOP
USING interrupt arrives before the subagent receives the MON_GET
request for processing.  This scenario keeps repeating as DMS
keeps running the query in the manner described above.
