[igraph] large graph problem

I use Igraph 0.5.2. The large graph has 4 Million nodes. 
It issues the following errors even I try to get the number of nodes in the graph.

malloc: *** mmap(size=551952384) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Assertion failed: (v->stor_begin != NULL), function igraph_vector_size, file vector.pmt, line 449.

So is there any way to fix it? how many nodes can be handled by Igraph?
