Hello list,
i've 36 servers all running vanilla 3.18.18 kernel which have a very
high disk and network load.
Since a few days i encounter regular the following error messages and
pretty often completely hanging disk i/o:
[535040.439859] do_IRQ: 0.126 No irq handler for vector (irq -1)
Did this happen right after you updated to 3.18.18?
Seems so.
Which kernel version were you using before that?
3.10.78
Have you observed such error messages before the update?
No.
All systems are Single E5 Xeons and I'm running irqbalance on them.
Does it stop if you disable irqbalance ?
No. The machines still crash.
Stefan
Thanks,
