Folks,


I am having a problem with the ADSpinnaker driver when I write to PVs rapidly from a client.  Here is what I see with all asynTrace enabled.  The camera is currently acquiring in "free-run" mode at about 110 frames/s.  The client stops acquisition (sets ADAcquire=0) and then configures the trigger mode PVs for a triggered acquisition.

*****************************

The detector is hung up at that point and I need to restart the IOC.

My question is what does this error mean and where does it come from?  I always see the message twice.

Error (511,511) PV: 13BMDPG1:cam1:TriggerOverlap ReadOut

I don't think it comes from areaDetector or asyn because those messages are all done with asynPrint and have timestamps.  It cannot be from the vendor library because it knows about the PV name.  So I am guessing it must come from base (7.0.3.1)?

This problem only happens when I am running the detector fast, 100 frames/s or more.  It does not happen at 50 frames/s.

Thanks,
Mark
