Hi,

	I got an erlang crash dump file on a 2G memory linux with following info:

eheap_alloc: Cannot allocate 78362800 bytes of memory (of type "heap").

=memory
total: 1510245164
processes: 1360838774
processes_used: 1360720438

	The total memory consumed by the VM was about 1.5G and most of them were used by  process. According to the process info in the dump file, the biggest Stack+Heap was 15672560 and the owner's state was garbing. I am not sure whether the process was the killer of the whole VM. 

Name	 	Spawned as	proc_lib:init_p/5
State	Garbing (limited info)	Last scheduled in for	xmerl_scan:'-initial_state0/2-fun-1-'/2
Started	Tue Nov 6 17:00:39 2012	Spawned by	<0.48.0>
Reductions	20600887
Stack+heap	15672560	OldHeap	8024355
Heap unused	202	OldHeap unused	8024355
Number of heap fragments	1	Heap fragment data	119
Program counter	0x02ea24dc (xmerl_scan:'-initial_state0/2-fun-1-'/2 + 4)
Continuation pointer	0x02e8a254 (xmerl_scan:scan_char_data/5 + 2408)
Arity	 
Link list	[#Port<0.16239279>, <0.48.0>]
Msg queue length	0


Is there a way to find out  which process  or function call was the reason of the allocating action, and how can I get more info from the dump file to help locating the error?

Thanks.
