Yes.

Indeed such crashes can happen in a system that does not have enough 
memory (e.g has less than 512M of RAM).

The Dialyzer version which will be part of R11B-5 improves significantly 
in this respect, but Erlang/OTP has no mechanism to gracefully recover 
when it runs out of memory (when it cannot allocate enough memory for a 
heap expansion).
