There's also
http://dieswaytoofast.blogspot.ca/2012/08/erlang-deep-bugs-at-least-one-of-which.html
from Mahesh in here, who found about some weird use cases of global that
would lock up code entirely while everything got serialized through a
single overloaded/busy gen_server.

This specific case was fixed back in R15B01, but maybe something similar
is at play here?
