Re: [Asterisk-Users] question about CPU usage
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

RE: [Asterisk-Users] question about CPU usage
Bill, I think your looking for setting the environment variable LD_ASSUME_KERNEL=2.4.1. If I remember correctly this effectively disables the new NTPL (new threading model) in RH9. Hope this helps.
