If the queue is defined as Not Shareable then every open for input will be
exclusive regardless of what the application asks for.
If the queue is defined as Shareable, then you can then you have three
choices open it as MQOO_INPUT_SHARED, MQOO_INPUT_EXCLUSIVE, or
MQOO_INPUT_AS_Q_DEF. Only the MQOO_INPUT_AS_Q_DEF will bother to use the
default input open option on the queue definition.
So with shared you have the option of either specifying in the code, or
deferring to the queue definition's default.
Sounds like your situation will always be exclusive. Therefore an orphaned
svrconn with an outstanding exclusive open can certainly get in the way and
what you describe is not unexpected. Either define the queue as shareable
if that was your intent, or you will need to manage these orphaned svrconn
instances. (Or maybe both)

The queue is defined with:
Sherability- Not Shareable
Default input Open Option- Exclusive
Are these related (especially the "shareability" option) ? It seems so, but
the interesting thing is that sometimes it (MQOPEN) succeeds and sometimes
it fails. I don't have a solid repro.
Thanks!,
Doron
