That's exactly what you are telling cfengine to do. "restart" is 
executed whenever the number of processes is either 0 or you sent a 
sigkill or sigterm to the process(es) via the signal option. Don't use 
it to stop a process.

What you are trying to do is probably this:

solaris.externalnets::
        "lpsched$"
        matches=0 # warn if a process was found
        signal=kill # it shouldn't be running at all,
                    # so the "hard" kill is OK.
        action=signal # the default, anyway: Send signal
                      # action=warn wouldn't send a signal.
        # if you list the "restart" option here, cfengine would
        # do the following three things on each run:
        # 1) warn if at least one process was found running
        # 2) kill any running process
        # 3) run whichever command you specify in the "restart"
        #    option

Read the doc about the processes section again ;-)
