I can plot my graph with DrL, and even layout.fruchterman.reingold

Any workaround (besides alternate layouts)?

You need at least about 13Gb of memory for that:

41295 * 41295 * 8 /1024 / 1024 / 1024

For 40k nodes, no layout will be good enough IMHO, unless you simplify the graph using communities or something along those lines.
