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?

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
