You have to modify gen_server to make error-proof message logging:

It is a pity, but current state of erlang error logging is error proof
only until large errors happen.
I don't know if my way of error limiting is ok for everyone:

or yours one is better, but I want OTP team to communicate about it.
gen_server:format_state is not enough because of dumping message queue
and error reason (it includes dumping state). Problem is larger and it
requires looking into all gen_ code and proc_lib infrastructure.

OTP is excelent software, but not ready for errors in large state
processes =(  I'm willing to help to fix it. Your patches are here, my
patches are here. RabbitMQ patches are available (they are so deep,
that R14 got even new instruction). Lets work out some best solution.
