I am not sure if Erlang's debugger (described in appendix E.2 on page 429 in the book

Joe Armstrong: Programming Erlang. Software for a Concurrent World.

(try to google this file:

	Pragmatic.Programming.Erlang.Jul.2007.pdf

)

is a kind of related work you are looking for. I have tried to use it but I did not like it.

One approach that worked for me is to record historical trace of processes, record it to file so
that I can later "go back in time" to see why something crashed or why something happed. The
aforementioned debugger cannot provide this kind of functionality. To be able to do that, I have to
intersperse my source code with small macros that record to logs
- - filename
- - line number
- - date and tim
- - (and optionally value of some relevant variable)
Recording that is laborious but it makes debugging possible (even though it is not very effective
way of doing things).
