Hi,
I have been using free radius for months for testing. Today, if just started giving me segmentation faults. Nothing has changed on the NAS or in the configs for freeradius so I have no idea why it suddenly is crashing. Is there some way to track down whats causing the segmentation fault? My log follows: or at least part of it
[root at localhost raddb]# radiusd -X
