Serve 2 https server{} block for 2 adress

Hey,
I successfully was able to set online a website in https ; but when I try to put a second one I get the following error :

""
[alert] 27063#0: worker process 27157 exited on signal 11
""

...Multiple time until the client does timeout.
There is the two https part, the two of them work if I disable one or another.
What am I missing ? :(
