ORBIT-USER: image nodes on grid failed June 7th morning

[Thierry Rakotoarivelo]

Dear Bin Zan and all,

Yesterday we upgraded imageNodes4. Before the upgrade, we tested the new 
version successfully on several node sets on the grid and the sandboxes. 
Unfortunately we did not try to image the entire grid at once, sorry 
about that.

I had a look at your logfile and it helped me track and correct a couple 
of bugs that did not show up previously.

I updated the software accordingly on the testbed today, and 
successfully managed to image a small sets of nodes (e.g. 33 or 19 nodes 
in grid_2007_06_08_03_14_52.log). However, imaging the entire grid at 
once still did not work. The problem seems to come from a bad handling 
of node failure notifications by the imageNodes process. I am working on 
fixing that bug.

In the meantime, I put back the previous imageNodes4 software on the 
grid (the one that used to be there before yesterday's upgrade). I 
tested it and managed to image 160 nodes on the grid (see 
grid_2007_06_08_04_18_01).

I apologize for the inconvenience caused by this update.

Kind regards,
Thierry.
