A segmentation fault is only ever caused by 2 things:

  * Hardware defect
  * Software defect

As a user there's very little you can do to resolve the problem - you need to run OTP under a debugger (such as GDB), find out what part of OTPd's code is broken, and fix it.

FreeRADIUS believes the otp check is failing. Unfortunately it doesn't say why. What version of FreeRADIUS are you running, 3.0.x may have some better instrumentation (or the developers may be able to add some).
