RE: PostgreSQL DB checkpoint error!

Classification: External

Hi David,

I am running cronjob at the same time which will do data pruning for zabbix database(psql).  Please let me know if that warning is related to reindex and vacuum ?

^C-bash-4.2$ cat /Data/zabbix_hkp/scripts/data_Pruning.sh

psql -d zabbix -f /Data/zabbix_hkp/scripts/three_months_datapurge.sql 1>/Data/zabbix_hkp/scripts_log/data_purging_`date +%m%d%y`.log 2>data_cleaning_err_`date +%m%d%y`.log

-bash-4.2$ cat /Data/zabbix_hkp/scripts/three_months_datapurge.sql
