hi, ..still on the path of the cause of the segfault. I put a suspicion on the TLS code feature new in 3.x - so disabled the virtual server that does TLS proxying....and just went to old school RADIUS for remote proxying.... the bad news is that there was still a segfault...the good news , I guess, is that without the TLS module, the server can run with -X - and therefore single threaded....so the cause of the crash might be slightly less opaque - have uploaded the relevant GDB output etc to bugs.freeradius.org (did find another fault too....is triggered in a different code path...in EAP section it seems....not related to the usual pre_proxy to proxy handling....have uploaded the relevant GDB of that too - bugs.freeradius.org) ...wont be long until we've squished these show stoppers. alan
