You are wrong. VM can survive such failures, but when failed state is
dumping, gen_server tries to send HUGE amount of data (yes, it doesn't
format, but it sends all data to error_logger) to error logger and
then everything fails. 50000000 of messages is a problem in dumping
format("** Generic server ~p terminating \n"
"** Last message in was ~p~n"
"** When Server state == ~p~n"
"** Reason for termination == ~n** ~p~n",
[Name, Msg, State, Reason1]),
Here Msg, State and Reason1 can be horribly big, that is why we _must_
limit them right here and I suppose, that best way is to print into
binary inside failing gen_server because there is one error_logger per
all cores and it may become a bottleneck.
