I've checked in some more fixes that might entirely solve the problems that everyone has been seeing. Unfortunately xen.bkbits.net is down and I'm about to leave for Canada. :-( Hopefully it will be possible to push to bkbits in a few hours... The Changesets that will hopefully fix everything are: 1.1116 04/07/20 11:32:39 kaf24@xxxxxxxxxxxxxxxxxxxxx +2 -0 More backend driver fixes and robustifying. 1.1115 04/07/20 11:14:24 kaf24@xxxxxxxxxxxxxxxxxxxxx +0 -0 Merge scramble.cl.cam.ac.uk:/auto/groups/xeno/BK/xeno.bk into scramble.cl.cam.ac.uk:/local/scratch/kaf24/xeno So keep an eye out for these when you pull --- we're very interested to hear of further bugs in builds /with/ these changesets. :-) -- Keir > I've just checked in a few networking fixes that should make things > rather more robust in low-memory conditions.
