With Vladimir help Sergey managed to start the replica manager changing a java option in replica.batch. This is as far as it goes because it still doesn't work, i.e. it doesn't produce replicas. We have just given Vladimir access to the testbed.
It seems Chris Brew is having the same 'cannot run more than 200 jobs' problem since he upgraded. He sent an email to the dcache user-forum. This makes me think that even if the replica manager might help it will not cure the problem.
