[10:19:57] davideagnello: there are a couple of changes that are required in order to address the issues related to this bug
[10:21:41] davideagnello: the first being where we persist all job related data
[10:21:54] davideagnello: the second, when we delete old job related data
[10:22:40] davideagnello: the issue is that zookeeper runs out of heap space because data we save to it is never deleted and overtime it runs out of heap space
