Under what conditions do you get the error?

[melvyn burnard]

Are you getting this error after typing in a command, or does this just appear in the system log?
Is it repeatable?
What version of OS is this?

i just want to understand in which satuation do you get this message?

i'm getting this message when i try to do init -q,

agetty is not running so i cant access server using console, i tries tracing the command using strace command, there i found this message

#strace -o /tmp/output /sbin/agetty -t 60 -L ttyS1 19200

i observe the following error message
