Subject: xspress3 internal triggering issue

I can no longer perform internally triggered data acquisitions with one of our 5 channel xspress3 units with dwell times that exceed 50 seconds. Last week I had set up a user that was doing 100 sec exposures with a weak source but over the weekend the IOC would stop the acquisition short, typically at around the 45 second mark, if not sooner. I have cycled all of the relevant hardware and controllers but the issue seems to persist. I can still seem to do long dwells with external triggers, but I appreciated the simplicity of utilizing internal triggers for the setup. Any thoughts?
