Does it happen repeatedly with the same message?
The error message includes two additional pieces of information (substituted
where '%s' is shown in the above code):
- the filename
- the error code from the operating system
So I suggest you post, verbatim, an *actual* instance of this error message
from your logs, as it would show what error the O/S has said occurred, and
therefore might point to what the problem is.
