I've tried doing an upgrade to 3.0.22 (built locally from source), all our tests pass but one with FreeRadius suffering a segmentation fault. It appears to be when FreeRadius attempts a status_check after getting no response from a server when it's attempting to proxy a request, specifically a request status check, a status-server check does not cause an issue and neither does no status check. (fulradiusd -X output at end of email) (0) Proxying request to home server 127.0.0.1 port 5555 timeout 2.000000 (0) Sent Access-Request Id 127 from 0.0.0.0:57856 to 127.0.0.1:5555 length 59 (0) User-Name = "paul" (0) Event-Timestamp = "May 26 2021 17:30:02 UTC" (0) NAS-IP-Address = 127.0.0.1 (0) Message-Authenticator := 0x00 (0) Proxy-State = 0x34 Waking up in 0.3 seconds.

(0) No proxy response, giving up on request and marking it done Marking home server 127.0.0.1 port 5555 as zombie (it has not responded in 2.000000 seconds). PING: Waiting 4 seconds for response to ping (1) Sent Access-Request Id 141 from 0.0.0.0:57856 to 127.0.0.1:5555 length 0 (1) User-Name := "test_user_please_reject_me" Segmentation fault (core dumped) The minimal configuration I've used to replicate the issue on top of the out of the box configuration, just adding to proxy.conf: home_server home_server_bt { type = auth ipaddr = 127.0.0.1 port = 5555 secret = secret response_window = 2 status_check = request username = "test_user_please_reject_me" password = "this is really secret" check_interval = 30 num_answers_to_alive = 3 } home_server_pool auth_pool_bt { home_server = home_server_bt virtual_server = virtual_server_bt } realm bt.com { auth_pool = auth_pool_bt } And an empty virtual server in sites-enabled: server virtual_server_bt { } I've tried to rule out anything environmental by trying this on builds on Ubuntu and Oracle Linux. I've also tried a build from head of the v3.0.x branch.
