High management CPU due to corrupted log index files

• High MP CPU
• Internal script is run every 15 minutes to generate bdx and idx index for different log types.
• Due to this script constantly running at high rate, it causes MP CPU to be high.
• The masterd_detail logs (less mp-log masterd_detail.log)  and indexgen.log ( less mp-log indexgen.log) display the failed messages
