no error messages were found on the log files of the bricks.<br>
<br>
The error messages appear on the client log files. Writing<br>

Note that if I try to write a directory with 480 6Mb files<br>
to /projects, over 3/4 of the files are written. It is<br>
random which files are not written (i.e. it is not the<br>
last 1/4 of the files which fail)<br>
