Description David Williams

I think this sort of bug, in the past, has been "fixed" by restarting the slave? Or ... Hudson?

I can certainly try a different slave, but ... seems we need all we can get. 

Thanks,

hudson slave 1 is building this just fine ... so, I think just slave 6 should be restarted (not master, I'm guessing).

Comment 2 Eclipse Webmaster

I've restarted slave6.

-M.

I think this was restarted, fixed, broke again, restarted again ... I better hurry and mark as fixed :)
