So as the one who did the 'battle testing' I should speak up :^) 

I did test tens of thousands of save/restore/migrations, but on 2.0.7-patch
i.e. on a version of the 2.0.7 tree with the save/restore fixes applied. 
This was not checked in directly to 2.0.7 since we aim to filter stuff 
through 2.0-testing and make a release that way. 

So it's extremely interesting to us if you have observed errors in 2.0-testing
since this might mean that something else is to blame (e.g. the upgrade from
2.6.11 to 2.6.12). This will delay our release of 2.0.8 which we were hoping
to do RSN. 

Can you possibly post some more details about what you observe? And what is 
in xend.log / xend-debug.log / xfrd.log? Is there a relatively small test
case that allows you to reproduce? 


thanks, 

S.

(p.s. as to the OP, I'm pretty sure the error he was seeing is fixed in 
both 2.0.7 and 2.0-testing)
