[Moose-dev] Fwd: [Pharo-project] Moose out of memory

IMHO although something is perhaps not completly clear in the vm in memory allocation and/or ui process and/or low space watcher (I tryed to debug the vm but did not succeed), here the problem seems to be in the Moose model. I suspect that the problem is just that the cache keeps a reference to the Moose model each time the script is run, see at the end of MooseScripts>>createModelForConfigurationOfMoose the model is added to a cache ((MooseModel root => MooseGroupRuntimeStorage>> byType) and takes abut 130M of memory each time. clearing the Moose cache resolve the problem. MooseModel allInstancesDo:[ :m | m remove ] seems to be working here, except that there is an exception for the root model (I don't know Moose, it may not be the best command). Perhaps the moose model should not be added by type but overriden each time (beeing identified by a "name" ?). PS: Moose is cool :) Cheers Alain
