[Freeipa-users] Login hangs / hung task?
Hello, I tried to login (ssh) to one (of three) freeipa systems running on CentOS yesterday without success. Running 'ssh root@service-2', the server would reply with a password prompt and then hang. I went to the system console to discover many of the following messages on screen: Jun 30 service-2 kernel: INFO: task sssd_be:22447 blocked for more than 120 seconds. Jun 30 service-2 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. Trying to login on the console, I was able to enter and username, but the login process would hang after entering the password. After rebooting the system, I see the following in /var/log/messages Jun 30 00:29:29 service-2 kernel: INFO: task sssd_be:22447 blocked for more than 120 seconds. Jun 30 00:29:29 service-2 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
