Hi, with that newest 3.0.x from today, I just got a crash (after some 15 min of normal operation, so nothing about stale EAP sessions this time). The directory in question exists (/var/log/radius/tlscache-eduroam-users/) but possibly there's simply no stored session if it's a fresh auth. I (again) don't have an easy way to get a full backtrace as this is happening on a live system, but maybe the below gives a hint already.
