memory leaks (blackberry playbook)

i have successfully ported a game to blackberry playbook using marmalade and cocos2dx.

the game gave some memory leak problems in the testing phase.

when i play the game continuously for sometime i.e. 45-50 minutes, then i get a message saying:-

“Memory debug manager max number of blocks reached. Memory metrics & posioning may not function correctly”.

can anybody please help me with this.
i hope that some one else also might have got this.
what should i do to solve this issue.

i googled it but didnt find any solution to it.

kindly help me with this.

Can you post up the full text from the log? Is that a Cocos2d-x message, or a Marmalade message?
