Hi Plesk Version: Parallels Plesk Panel v9.5.4_build95101209.05 os_CentOS 5 OS: Linux 220.127.116.11-xxxx-std-ipv6-32 Since upgrading PHP to 5.3 (5.3.8-1 to be exact), our Scheduled Tasks / Cronjobs have not been running. I noticed this because our backup tasks have not run since the upgrade. I have checked the log at /var/log/cron and there are entries every 15 minutes for the backup task which is supposed to only run once at 03:00 every day and backup the server settings and content. The entries look like this: Nov 24 13:57:01 ks359302 crond: (root) CMD (/usr/local/psa/admin/sbin/backupmng >/dev/null 2>&1) So, the task is being logged, but is not being processed. I have run the following test: cd crontab -l > crontab.orig echo "* * * * * /usr/bin/date >> $HOME/cron_work.log" > crontab.file crontab crontab.file touch cron_work.log tail -f cron_work.log Again, the job is logged in /var/log/cron, but the cron_work.log file is empty. I have searched the forums for advice, but have mainly found advice for similar problems in Plesk 10. If anyone knows of cronjob issues when upgrading Plesk 9 to PHP 5.3, I would greatly appreciate the advice.
