[Asterisk-Users] question about CPU usage

[Jason Becker]

Back in February I found * pinning the CPU (Slackware 9.1, Feb CVS). I 
ran a strace and found that it was looping on this:


> -begin-
>
> write(1, "\nUse STOP NOW to shutdown Asteri"..., 35) = -1 EIO
> (Input/output erro
> r)
> write(1, "*CLI> ", 6)                   = -1 EIO (Input/output error)
> read(0, "", 1)                          = 0
> ioctl(0, SNDCTL_TMR_STOP, {B38400 opost isig icanon echo ...}) = -1 EIO
> (Input/o
> utput error)
>
> -end-

Mark kindly responded to me:

-begin-

In the mean time try running asterisk with no console.  This is bug #864.
Preliminary analysis shows that after a "restart now", one of the
ioctl()'s performed by editline fails with "-1".  Ignoring the ioctl made
the CLI non-functional.  Happy to get any help I can in this regard.

-end-

Hope this helps.

Cheers
