Hi:
>I was wondering if anyone might know what could be causing the error in the attached screenshot. This is from an EPICS IOC with custom device support running on Windows. It or a similar error >seems to occur at random times and requires the IOC to be restarted.
(screenshot shows cbLow/cbHigh ring buffer overflow)
I think you can get an overflow of the callback buffer if you have device support that uses SCAN=I/O Intr and calls
scanIoRequest() faster than the callback task can process the requested callbacks.
