Ubuntu 11.10 post-update problem

Asked by Sitov Cristian

I have a Ubuntu x64 machine on a OpenVZ VPS account on a QuadCore processor with 1GB/2GB(burst). A few days ago I've managed to successfully update it to 11.10 Oneiric Ocelot. There's only one problem: my "init" process (PID = 1) is at 100% CPU usage, keeping one core 99.5% of the time at full throttle.

Is there any solution to stop the strange init's behavior? Can I trace what happens behind that init process to find out what makes it spike so high?

Do you use proprietary drivers?

i have same issue here

i tried to strace init from hardware node:
waitid(P_ALL, 0, {}, WNOHANG|WEXITED|WSTOPPED|WCONTINUED, NULL) = 0
clock_gettime(CLOCK_MONOTONIC, {523235, 243099900}) = 0
select(6, [0 2 3 4 5], [], [2 4 5], NULL) = 1 (in [0])
read(0, "", 1) = 0
waitid(P_ALL, 0, {}, WNOHANG|WEXITED|WSTOPPED|WCONTINUED, NULL) = 0
clock_gettime(CLOCK_MONOTONIC, {523235, 243523268}) = 0
select(6, [0 2 3 4 5], [], [2 4 5], NULL) = 1 (in [0])
read(0, "", 1) = 0
.....

i use 2.6.32-042stab039.3 openvz kernel on hardware node

i created clean oneiric machine with debootstrap and rsyslog and init eats 100% cpu

My hardware node is a 32bit debian 6.0 with linux-image-2.6.32-5-openvz-686 (=2.6.32-31)
