[erlang-questions] Slave node restart not working

[Adam Lindberg]

I can see that the new beam process for the slave node actually 
dissappears, and it and it is not possible to ping it.

I have verified this behavior on Windows as well.


» ps aux | grep beam | wc -l
1

(hest@REDACTED)24> net_adm:ping(apa@REDACTED).
pang
(hest@REDACTED)25> net_adm:ping(apa@REDACTED).
pang
(hest@REDACTED)26> slave:start(yama, apa).
{ok,apa@REDACTED}
(hest@REDACTED)27> net_adm:ping(apa@REDACTED).
pong

» ps aux | grep beam | wc -l
2

(hest@REDACTED)28> rpc:call(apa@REDACTED, init, restart, []).
ok
(hest@REDACTED)29> net_adm:ping(apa@REDACTED).
pang
(hest@REDACTED)30> nodes().
[]

» ps aux | grep beam | wc -l
1


Cheers,
Adam
