Report Viewer: Error writing file

I have a Report Viewer and within that report viewer I have a custom property where the binding is Tag History.
I’m having this error:

[quote]Exception: Error running query:
TagHistory(paths=[tag1, tag2, tag3], start=Fri Apr 18 00:00:00 PDT 2014, end=Wed Apr 23 00:00:00 PDT 2014, flags=0)@0ms

caused by SQLException: Error writing file ‘/home/tmp/MYE779I5’ (Errcode: 28)[/quote]

How can I fix this error?

Thank You
