Hi,

Yesterday one of our busses went partially bad. Every few seconds the readings from all devices from the bus would indicate that there was a read error. Then the next read would succeed. One suggestion to handle these situations was to only signal an error afer N number of bad readings in a row. Has anyone attempted to handle this situation with EPICS? Any suggestions?

I know that the correct way to handle this is fix the problem ASAP but I don't enjoy calling in a support team in the middle of the night.

Thanks for your comments.

Geoff
