It seems we hit some bug, because every node has got enough memory to run the resource, taking into account the node/resource memory settings. Still, lx0 was not started. >From debian squeeze backports pacemaker 1.1.7 is available instead of our running version 1.1.6, but the changelog doesn't say anything about utilization related fixes.
