The syntax for "ps" varies, as does the output. Please post which Operating System you have.

Btw. When you have multiple CPUs the percentage from "ps" is a percentage of one CPU. Thus a single process could run at 100% CPU without having any adverse effect. The more CPUs you fit to the computer the more likely you are to see processes with a very high CPU percentage.

Detecting a looping process is a fine art and I don't think that a single snapshot of the CPU percentage is useful for deciding whether to kill a process. It is unlikely that you would come up with a single command line which would be safe to run in a commerical environment.

A perfectly sized and perfectly tuned computer would have everything running at 100% with no wait states.

vsig

vsig(1F)                                                           FMLI Commands                                                          vsig(1F)

NAME

       vsig - synchronize a co-process with the controlling FMLI application

SYNOPSIS

       vsig

DESCRIPTION

       The  vsig  executable  sends  a  SIGUSR2 signal to the controlling FMLI process. This signal/alarm causes FMLI to execute the FMLI built-in
       command checkworld which causes all posted objects with a reread descriptor evaluating to  TRUE to be reread. vsig takes no arguments.

EXAMPLES

       Example 1: A sample output of vsig command.

       The following is a segment of a shell program:

       echo "Sending this string to an FMLI process"
       vsig

       The vsig executable will flush the output buffer before it sends the SIGUSR2 signal to make sure the string is actually in the pipe created
       by the cocreate function.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE         |      ATTRIBUTE VALUE        |

       +-----------------------------+-----------------------------+

SEE ALSO

       coproc(1F), kill(1), kill(2), signal(3C), attributes(5)

NOTES

       Because vsig synchronize with FMLI, it should be used rather than kill to send a SIGUSR2 signal to FMLI.
