Turned out it did, but with a higher threshold.
As soon as we started testing with files > 100Mb the same behaviour  
came up again.

It turned out to be another bug related to reiserfs.

For those interested more data is here:
http://sourceforge.net/mailarchive/forum.php? 
forum_id=4930&max_rows=25&style=flat&viewmonth=200511&viewday=1

and here:

In short: Although reiserfs reports in it's FAQ that it supports  
filesystems up to 16Tb with the default options (4K blocks) it  
supports only 8Tb. It doesn't fail however and appears to work  
correctly when using the local filesystem, the problems start showing  
up when using NFS

I fixed the problem by using another filesystem. Based on comments on  
the nfs-ml and the excellent article in last months linuxgazette we  
switched to jfs.
So far it's holding up very good. We haven't seen the problems  
reappearing with files in excess of 1Gb

Thanx for the help though.

Ramon
