Data Background processes return 127 sporadically
I have created a shell script that spawns multiple background processes (spawns sqlplus application). I use an array to capture the process id of those background processes. I then loop through the array and issue a 'wait' command to wait on the process id that was captured in the array. I am getting sporadic results where some of the background processes return an exit code of 127.

It seems possible that it may be related to the OS because I get different results on different machines. Sun OS 5.6 I get sporadic results. Sun OS 5.8 seems to be OK.

Output results to show inconsitency:
--Run 1
Process: 0 PID: 13718 Return Value of: 0
Process: 1 PID: 13721 Return Value of: 0
Process: 2 PID: 13724 Return Value of: 0
Process: 3 PID: 13727 Return Value of: 127
Process: 4 PID: 13730 Return Value of: 0
--Run 1
Process: 0 PID: 20849 Return Value of: 0
Process: 1 PID: 20852 Return Value of: 127
Process: 2 PID: 20855 Return Value of: 127
Process: 3 PID: 20858 Return Value of: 127
Process: 4 PID: 20861 Return Value of: 0
--Run 1
Process: 0 PID: 21688 Return Value of: 0
Process: 1 PID: 21691 Return Value of: 0
Process: 2 PID: 21694 Return Value of: 127
Process: 3 PID: 21697 Return Value of: 0
Process: 4 PID: 21700 Return Value of: 0
--Run 1
Process: 0 PID: 23945 Return Value of: 0
Process: 1 PID: 23948 Return Value of: 0
Process: 2 PID: 23951 Return Value of: 0
Process: 3 PID: 23954 Return Value of: 0
Process: 4 PID: 23957 Return Value of: 0

Any ideas?????

killall5

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME

       killall5 -- send a signal to all processes.

SYNOPSIS

       killall5 -signalnumber [-o omitpid[,omitpid..]]	[-o omitpid[,omitpid..]..]

DESCRIPTION

       killall5  is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so
       it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d
       directory.

OPTIONS

       -o omitpid
	      Tells killall5 to omit processes with that process id.

NOTES

       killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program.

EXIT STATUS

       The  program  return  zero  if  it  killed  processes.  It return 2 if no process were killed, and 1 if it was unable to find any processes
       (/proc/ is missing).

SEE ALSO

       halt(8), reboot(8), pidof(8)
