Terminating application during startup

[Gunilla Arendt]

Hi,

This bug is fixed in OTP R11B.

I'm not quite sure what you mean with "terminating nicely". If you mean
that you want the node to survive even if an application fails to start,
set the type of the application to transient in the .rel file.

Regards, Gunilla
