I have not been able to reproduce this, though it sounds like a file system 
related race condition is triggering the re-load.  Can you give me some 
details like OS, filesystem, local or remote, media type, data accumulation 
rate (fields/row and rows/s), file format, etc.

I also can't reproduce this.  Can you give me details (OS, file size)?  Is the 
data being updated real time during the read?  At what rate?

Yes.... are you using smb or nfs?  Is it at all correlated with the first bug?
