kill a process if grep match is found

Hi,

I need something unusual, I guess. I need to start a process, and if that process displays a specific error message, I need to kill that process and restart it.

Something like:
Code:
startprocess | grep -i "This is the specific error message" && kill $pidof(startprocess)

Explanation, I need to start the process, check if it echoes any messages and if any of them is the one that I'm waiting, I need to kill that process.

Restarting of the process I can do putting all this in a while loop or something.

Is this possible at all? Is there any easier way to accomplish the same thing?

Thanks for any help in advance.

KILL(1) 						      General Commands Manual							   KILL(1)

NAME
kill, broke - print commands to kill processes SYNOPSIS
kill name broke DESCRIPTION
Kill prints commands that will cause all processes called name and owned by the current user to be terminated. Use the send command of 81/2(1), or pipe the output of kill into rc(1) to execute the commands. Kill suggests sending a kill note to the process; the same message delivered to the process's ctl file (see proc(3)) is a surer, if heavy handed, kill, but is necessary if the offending process is ignoring notes. Broke prints commands that will cause all processes in the Broken state and owned by the current user to go away. When a process dies because of an error caught by the system, it may linger in the Broken state to allow examination with a debugger. Executing the commands printed by broke lets the system reclaim the resources used by the broken processes. SOURCE
