unusual problem with cp command

I have made a simple script to zip a file then first copy it to a specific directory using cp command then move it to another directory. Files are getting generated at regular intervals in the dir. /one/two/three/four/. I have entry of my script in cron to run after every 2 min.
Code:
#!/bin/sh
date2=`date +%Y%m%d`
hstname=`hostname`
LOG_FNAME=Med_Gzip_"$date2"_"$hstname".txt
LOG_FILE_PATH="/one/two/three/ZIP_CDR_SCRIPT/$LOG_FNAME"
for FNAME in /one/two/three/four/MUM_NG2_*.cdr
do
   gzip "$FNAME"
   echo "Zipped File name : $FNAME " >> $LOG_FILE_PATH
   cp -p "$FNAME".gz /one/two/three/five/
   First_FNAME=`echo $FNAME |cut -d'.' -f1`
   Archive_FNAME="$First_FNAME"_Archived.cdr.gz
   mv "$FNAME".gz $Archive_FNAME
   mv $Archive_FNAME /one/two/three/five_archive
   date1=`date +%Y%m%d_%H%M%S`
   echo "ZIP FILE TIMESTAMP: $date1 " >> $LOG_FILE_PATH
   echo "********************" >> $LOG_FILE_PATH
done

Problem:
All zip files in the directory /one/two/three/five_archive are as expected but the files generated in the directory /one/two/three/five/ sometimes(randomly time interval in 4 to 10 days) have zero size and owner and group of the files are also gettnig changed to root. Permission also getting changed to 400 from 644.
No idea why this is happenning randomly, After every random number of days we are reported issue with file permission, owner, grop getting changed for few files.
Have anyone experienced same issue ever. Is there some issue with cp command. Any help would be highly appreciated.

NAME
mvdir - move a directory SYNOPSIS
dir newdir DESCRIPTION
moves one directory tree into another existing directory (within the same file system), or renames a directory without moving it. dir must be an existing directory. If newdir does not exist but the directory that would contain it does, dir is moved and/or renamed to newdir. Otherwise, newdir must be an existing directory not already containing an entry with the same name as the last pathname component of dir. In this case, dir is moved and becomes a subdirectory of newdir. The last pathname component of dir is used as the name for the moved directory. refuses to move dir if the path specified by newdir would be a descendent directory of the path specified by dir. Such cases are not allowed because cyclic sub-trees would be created as in the case, for example, of which is prohibited. does not allow directory to be moved.
