accel-ppp stops processing packets when RADIUS is unavailable
Posted: 06 Dec 2020, 07:59
Hi
I've noticed accel-ppp stops processing packets for PPPoE and L2TP type services when RADIUS services become unresponsive or slow. My guess is that the request queue is overwhelmed with RADIUS requests and it stops or slows processing others to almost a halt as all threads become busy/overwhelmed. This is on a very busy server doing > 2Gbps.
[radius]
server=1.2.3.4,password,auth-port=1812,acct-port=1813,req-limit=50,fail-timeout=10,max-fail=10,weight=5,acct-interim-interval=900
acct-interim-interval=900
verbose=1
interim-verbose=300
max-try=3
acct-timeout=120
It's a major issue that a failure in the control plane can severely affect the data plane. Is there any suggestions on possible configuration solutions or otherwise, should the thread queues for data plane and control plane issues be separated?
Thanks
