XSPRESS3 error messages

[John Dobbins via Tech-talk <tech-talk at aps.anl.gov>]

All,

I don't think this is an EPICS issue but I am asking in case anyone might have related experience.

We have a four channel XSPRESS3, which is 10+ year old.  This has the older hardware format in which a single card hosts up to 8 channels.  This past January I updated the IOC from the original IOC to

https://github.com/epics-modules/xspress3

the build_xspress3.py script at the time called out 

'xspress3': 'xspress3-2-4.tar.gz'

which is see has since been updates to 

'xspress3': 'xspress3-2-8.tar.gz'

The new IOC runs, though the data is sporadically noisier than with the old IOC. Also, we get error messages at the IOC console like:

epics> Received data from wrong channel = 0 at path=0, card=0, chan_of_card=3

I see that the messages come from the xspress3 library and not the EPICS source code.

Regards, any help appreciated.
