[erlang-questions] how to access process heap from outside the process

[dzejefkej]

hi,
 I need to sniff state of the process.
 It is gen_srv or gen_fsm executing synchronous call, so it ignores sys:get_status/1 or /2. 
 process_info is also not very helpful.
 What is the simplest way to access StateData or dump and decode the heap?

regards,
D
