the new nodes could confirm that : look for the IP of an old node and maybe you'll find hinted
handoff related messages.

I grepped on every node about every old node, I got nothing since the "crash".

If it can be of some help, here is some grepped log of the crash:

Maybe its the way I have removed nodes ? AFAIR I didn't used the decommission command. For
each node I got the node down and then issue a remove token command.
Here is what I can find in the log about when I removed one of them:
