[erlang-questions] hanging nodes
Wed Aug 20 15:08:55 CEST 2014
This is most probably a windows only issue as the code in the stacktrace
runs through a lot of windows specific code. I guess the easiest way would
be if you are able to write a testcase that can reproduce the error so that
I can debug it here. If that is not possible, maybe you can attach to the
process and send me a windows "core file"?
To do this you have to install WinDbg and then do "File->Attach to a
Process". After this you open the WinDbg console and type ".dump /ma
c:\beam.smp.dmp" and then upload that file on a server where I can download
it. Also I assume you have used one of the installers on erlang.org? Which
version of windows+Erlang/OTP are you using?
