Problem with 2.1.10 hanging
My 2.1.10 server I got compiled has a problem where it hangs after a few hours. I'm not sure if it's related to the number of requests it's processed or not. It's happened three times so far. Restarting the server always gets it working again. Using tcpdump I can confirm that it's receiving requests from the NAS but not processing them. Using strace I can see that it's stuck on a futex: write(1, "Wed Aug 25 16:13:45 2010 : Info: "..., 70) = 70 futex(0x827fe88, FUTEX_WAIT_PRIVATE, 2, NULL The server is doing nothing more than EAP-TLS authentication for some wireless AP's. Debug from the config loading and the last few packets are below. Alan, let me know if you'd rather have this type of thread on the Developer list instead of the User list.
