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.
