In addition to this, "timeout server" doesn't affect the connect timeout, only the transfers. It's "timeout connect" which affects the connect timeout. Hoping this helps, Willy
Re: Higher Tc than timeout server
Hi, Sorry to bump this, but I haven't made any progress with this on my own. Does anyone see what I'm missing here? William Edwards schreef op 2022-05-26 12:10: Hi, The Tc timer is documented as: - Tc: total time to establish the TCP connection to the server. It's the time elapsed between the moment the proxy sent the connection request, and the moment it was acknowledged by the server, or between the TCP SYN packet and the matching SYN/ACK packet in return. The value "-1" means that the connection never established. The `timeout server` option is documented as: The inactivity timeout applies when the server is expected to acknowledge or send data. However, I have a few connections with a higher Tc than `timeout server` (5m), e.g.: May 25 20:15:33 admin-msh haproxy[1015]: :::127.0.0.1:33406 [25/May/2022:03:18:44.905] redis redis/http-msh02.efw.ha.cyberfusion.cloud 1/0/61008353 87670 -- 134/113/112/112/0 0/0 Shouldn't the `timeout server` have closed the connection with the sD termination state after 5m if it took 61008353 ms for the server to acknowledge the connection request? Or, more likely, am I misreading the documentation? Full config is attached. Used HAProxy version is 2.2.9-2. -- With kind regards, William Edwards
Higher Tc than timeout server
Hi, The Tc timer is documented as: - Tc: total time to establish the TCP connection to the server. It's the time elapsed between the moment the proxy sent the connection request, and the moment it was acknowledged by the server, or between the TCP SYN packet and the matching SYN/ACK packet in return. The value "-1" means that the connection never established. The `timeout server` option is documented as: The inactivity timeout applies when the server is expected to acknowledge or send data. However, I have a few connections with a higher Tc than `timeout server` (5m), e.g.: May 25 20:15:33 admin-msh haproxy[1015]: :::127.0.0.1:33406 [25/May/2022:03:18:44.905] redis redis/http-msh02.efw.ha.cyberfusion.cloud 1/0/61008353 87670 -- 134/113/112/112/0 0/0 Shouldn't the `timeout server` have closed the connection with the sD termination state after 5m if it took 61008353 ms for the server to acknowledge the connection request?
