All queues are defined with DEFBIND(NOTFIXED)...and the appl has MQOO_BIND_NOT_FIXED
specified. What could be causing the error?

If a clustered queue manager is unreachable or unavailable due to a network error or a QMGR going down or a server crashing... whatever scenario you can think of that would
make a QMGR 'unavailable', the cluster channels to the unavailable QMGR go into a
retrying state. Workload continues to be 'destined' to this unavailable
QMGR. The channels being in a retrying state is not treated as an 'error' condition
and therefore the cluster workload balancing (round-robin) contines to consider this QMGR
as available.

Hi,
Are you shure that the QMGR-name isn't explicitely stored in the MQMD from the application programmer ?

Yes. If you are issuing the MQOPEN and specifying a QMGR/Queuename pair instead of just the queuename, it will always resolve to that instance of the queue, and no workload balancing will occur.
