Can it be that several records have queued up on the asyn port when the
ioc exits? In that case scanning would already have been stopped, but
still records may be scheduled to access the port when the ioc is
already shutting down. Maybe I need to check the ioc run state and
discard all queued records when the ioc is shutting down.
Also this behavior may be a side effect of the new cases in that the
@init handler is supposed to run, namely after asyn port re-connect and
after ioc resume (iocRun). I need to check...

Hi
We are using the following setup to test control of the agilent XGS
gauge controllers and Gamma ion pump controllers:
1.EPICS Base 3.15.6
2.Asyn R4-33
3.Stream R2-7-7c
For agilent controllers we get the following error:
asynError in write. Asyn driver says: device:port disconnected.
But eventually the IOC exits. For the gamma controllers we get something
really strange. There a point in the database where the IOC never exits,
the exit command just freezes and Ctrl-C is the only way to shut down
the IOC. For now I can see that this behavior occurs because more DB
substitutions are configured which means more PVs and more controllers.
But that was not the case when we had:
1.EPICS Base 3.14.12.3
2.Asyn R4-18
3.Stream R2-5-1
Where the IOC exits with no errors or freezing. Should we upgrade our
support modules or change the EPICS base?
Another problem we are facing with this new setup is that I can't find
some asyn IOC shell function like asynTraceMask for example. The IOC is
configured properly in RELEASE and src/Makefile. Is there anything we
miss in the new setup?
