I am running a test script where in a loop of 800, two crontab scripts create new crontab in a duration of 5 seconds.Eg.while [ $counter -lt 800 ]; do    crontab -r    create_crontab_1.sh >> cr_log.log    sleep 5;    create_crontab_2.sh>> cr_log.log    (( counter++ ))doneNowcreate_crontab_1.sh->CRONLINE=*/2 * * * * /scratch/test1.sh >/dev/null 2>&1( crontab -l 2>/dev/null ; echo ${CRONLINE} ) | crontab -  create_crontab_2.sh->    crontab cron_file.txtcron_file.txt ->    * * * * * sleep 2; /scratch/test3.sh >/dev/null 2>&1    * * * * * sleep 3; /scratch/test4.sh >/dev/null 2>&1  /var/log/cron log:crond[25583]: (user_name) RELOAD (/var/spool/cron/) CROND[29339]: (root) CMD (sleep 3; /abc/test3.sh >/dev/null 2>&1) CROND[29340]: (root) CMD (sleep 2; /abc/test4.sh >/dev/null 2>&1) crontab[29345]: (user_name) LIST () CROND[29353]: (user_name) CMD (/abc/test1.sh >/dev/null 2>&1) crontab[29365]: (user_name) REPLACE ()  Even when crontab with test1.sh gets overwritten in 5 seconds, why does test1.sh comes in cron log, and can be seen getting invoked every 2 mins (as it is scheduled to run every 2 mins) ??Also does it have anything to do with CPU clock?
cron log shows old cron job being executed?
