Hi, Just to keep you posted, upgraded our cluster yesterday to a custom compiled 0.56.1 and it has now been more than 24h and there is no sign on memory leak anymore. Previously it would rise by ~ 100 M every 24h almost like clock work and now, it's been slightly more than 24h and memory is stable. (it fluctuates, but no large jumps that stay forever).
