tincd gives kernel general protection ip error.

[Lance Fredrickson]

The issue seems to have subsided, I can't get it to crash anymore. I'm 
guessing maybe something in the environment that changed. For the heck 
of it I also tried the static musl libc version on the other server that 
has not had issues, and it has been running  for > 1 week just fine. 
I'll post back with some debugging if it ever happens again.
