The test
Code:
if [ -e ${FOLDER}/${PID} ]

does not accept multiple values this way. Putting a set -x in the head of your script shows following:
Code:
+ '[' -e home/optima/pids/optimamd_opx_LOD_GEN_110_00111009A.pid home/optima/pids/optimamd_opx_LOD_GEN_110_001110106.pid
 home/optima/pids/optimamd_opx_LOD_GEN_110_001110107.pid home/optima/pids/optimamd_opx_LOD_GEN_110_001110109.pid
 home/optima/pids/optimamd_opx_LOD_GEN_110_00111010H.pid home/optima/pids/optimamd_opx_LOD_GEN_110_00111010L.pid ']'
./mach.ksh: line 10: [: too many arguments
+ echo -e '*.pid not found.'
*.pid not found.

I suggest to put it this way and do not test with -e if the files exist, as the loop will only run on the files that fit to the expansion anyway and sowith exist:
Code:
for f in ${FOLDER}/*pid; do
   ls_time=`...
   ...
done

You will also get problems with these kind of cuts:
Code:
cut -d\ -f 8 | cut -d\: -f 1

If you want a blank as delimeter, write it like this:
Code:
cut -d" " -f 8 ...
#or
cut -d\  -f 8 ...

In the second line there are 2 blanks so cut will know that only the following blank right after the backslash is the delimeter, not the rest of the command too. I'd suggest you take the 1st solution as it is more clear to read.

And another more general thing is, that the programs or scripts that generate those pid files, should be able to clean them up themselves. It seems that there is something not working properly and that this script is just a workaround for the real problem.

pidof

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

NAME

       pidof -- find the process ID of a running program.

SYNOPSIS

       pidof [-s] [-x] [-o omitpid] [-o omitpid..]  program [program..]

DESCRIPTION

       Pidof  finds  the  process  id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems
       used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts  are  located	in
       /etc/rc?.d, where ? is the runlevel. If the system has a start-stop-daemon (8) program that should be used instead.

OPTIONS

       -s     Single shot - this instructs the program to only return one pid.

       -x     Scripts too - this causes the program to also return process id's of shells running the named scripts.

       -o     Tells  pidof  to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof pro-
	      gram, in other words the calling shell or shell script.

NOTES

       pidof is simply a (symbolic) link to the killall5 program, which should also be located in /sbin.

       When pidof is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is  possible  that
       it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs.
