The problems are probably less frequent than that. And a beamline might be 4 IOCs.
The issues tend to arise during power or network failures when the vxWorks VME IOC is in the middle of saving the file via NFS.
There are safeguards now in place that make this much less likely. And there are backup files created by the autosave system that can be recovered from.

Hello again,
I was looking at autosave record/functions.
I read that APS is experiencing at least 1 autosave issue per beamline,
per year. Can anyone expend on that?
I assume that files are being corrupted or such...
How could that happen?
