Hi, I am running vanilla kernel 3.0.23 . I am trying to add some 6K and more IPv6 IPSec tunnels. I am getting these warnings in dmesg close to 6k tunnels, after which the kernel hangs and have to reboot the kernel. [ 1511.045261] INFO: rcu_sched_state detected stall on CPU 4 (t=300000 jiffies) [ 1534.736899] INFO: rcu_bh_state detected stalls on CPUs/tasks: { 4} (detected by 13, t=300002 jiffies) I am not getting any back-trace also, to figure out what is actually causing the stall to happen. Could someone help to figure out the issue. Regards, Prashant |
