Thats pretty easy, it means that your program (is it really coming from the MQ Broker?) is doing MQGET with MQGMO_SYNCPOINT and never issuing an MQCOMMIT. Normally, a pattern is:
MQGET with SYNCPOINT
do your work
MQCOMMIT
get another message.
Tell us more about this program that is giving this error message.
btw, the default is 10,000 message under one unit of work, you can change that with ALTER QMGR MAXUMSGS(<new value>), but I wouldn't suggest it as a remedy until your are certain you really need to.

Wayne,
Wonderful!!!!!!!!!!
It worked.The program was entering an infinite loop trying to GET messages.
Here is what was happening:
Three queues were planned in coding stage:
req1,rep1,err1
During system testing,since the reply queue would be remote,we decided to use err1 as reply queue for some initial testing and there it all began.
Our code searches for messages on error queue first,if there are any messages on the error queue it copies those messages onto the reply queue.If not then it picks the message from the request queue for procesing.
First message sequence of action:
Put message in request queue
Search message on error queue-no messages as this is first message
Message read from request queue
Message put in reply queue(in this case it was err1 queue)
Second message sequence of action:
Put message in request queue
Search message on error queue(err1)-there is a message here due to first message
Copy this message (which is in err1) to reply queue(which is again err1).
!!!!!!!!!!!!!!LOOPING !!!!!!!!!!!!!!!!!!
Results in syncpoint error.
Thanks a lot Wayne for such a quick response.
