The old sysstat cron job continues running in parallel with the new one.

Solution In Progress - Updated -

Issue

  • The old sysstat cron job continues running in parallel with the new one.

  • The old one was as follows. This ran sar1 599 times at a second interval:

# run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib64/sa/sa1 1 599
# generate a daily summary of process accounting at 23:53
53 23 * * * root /usr/lib64/sa/sa2 -A
  • The new one. I changed it back to the default:
# run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib64/sa/sa1 1 1
# generate a daily summary of process accounting at 23:53
53 23 * * * root /usr/lib64/sa/sa2 -A
  • However the sadc process started from the above-mentioned previous systat cron job setting keeps on running. It starts again and again every 10 minutes even though I kill the process:
ps -ef | grep sadc
root     10392 10391  0 18:00 ?        00:00:00 /usr/lib64/sa/sadc -F -L 1 599 -
