Hi Kevin,

I am pretty new to DTN2, so not really the best person to give advice.
However, I did come across a similar spin lock error during my recent
testing.
In my case, the spin lock error was a symptom of an unrelated problem i.e a
red herring, I ended up fixing my problem by updating my configs.
This view is also shared by the N4C project, who hid the spin lock error by
changing the log level to INFO/NOTICE.

http://www.n4c.eu/Download/8.4/n4c-wp8-006-M8.5-summer_test_2010_Slovenia_V06.pdf

Good luck fixing your problem.

Kind Regards,
Nik
