radius crashing

MessageI am having a problem with freeradius 1.1.6 crashing unexpectantly. Only once has it given the error Jun 9 13:32:35 radius freeradius[16938]: Assertion failed in util.c, line 190 Jun 9 13:32:35 radius freeradius[17330]: Assertion failed in threads.c, line 394 As of yet I have no idea what might be causing this.
