One of my two Radiator boxes is exhibiting very high memory usage for its radius process: 15211 root 16 0 12 10:28.09 44.5 457m 450m 3248 R radiusd After a restart (stop/stop, not a SIGHUP) of that radius process, the memory usage drops temporarily but then climbs again. Could a misbehaving NAS cause this? Andrew Clark
