[erlang-questions] How to connect erlang nodes over IPv6 (on Ubuntu 10.04 server installations, Erlang R14B1)?
Mon Feb 14 23:26:47 CET 2011
Using the git-source as a base, I build a new version for testing.
The only difference of the source was, that I removed the "&&
defined(EPMD6)" from "erts/epmd/src/epmd_int.h".
After starting "empd -d" and running "erl -name test1 -setcookie
abc123 -proto_dist inet6_tcp" I got a "erl_crash.dump".
Using a new "erl" instance, I called "crashdump_viewer:start()." and
tried to load the "erl_crash.dump" file, but I always get "An error
occured: C:\fakepath\erl_crash.dump is not an Erlang crash dump"!
Looking into "erl_crash.dump" the first few lines are:

Is the "crashdump_viewer" broken?
Are there any other tools to "analyse" an "erl_crash.dump" file?
