Ubuntu 14.04 x64 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Multi-server setup, sync of /var/www /var/vmail via unison. Here is a sample of what syslog shows : Code: Jan 1 08:13:01 comeon CRON[9349]: (root) CMD (/usr/bin/unison &> /dev/null) Jan 1 08:14:01 comeon CRON[9382]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done) Jan 1 08:15:01 comeon CRON[9409]: (root) CMD (if [ -x /etc/munin/plugins/apt_all ]; then munin-run apt_all update 7200 12 >/dev/null; elif [ -x /etc/munin/plugins/apt ]; then munin-run apt update 7200 12 >/dev/null; fi) Dec 28 02:34:01 comeon CRON[9407]: (root) CMD (/usr/bin/unison &> /dev/null) Jan 1 08:15:01 comeon CRON[9410]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done) Jan 1 08:15:01 comeon CRON[9411]: (root) CMD (/usr/bin/unison &> /dev/null) Code: Jan 1 08:25:01 comeon CRON[11144]: (getmail) CMD (/usr/local/bin/run-getmail.sh > /dev/null 2>> /dev/null) Jan 1 08:26:01 comeon CRON[11625]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done) Jan 1 01:51:01 comeon CRON[11628]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done) Jan 1 08:26:01 comeon CRON[11628]: (root) CMD (/usr/bin/unison &> /dev/null) Jan 1 08:27:01 comeon CRON[11854]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done) Code: Jan 1 09:03:02 comeon CRON[18087]: (root) CMD (/usr/bin/unison &> /dev/null) Jan 1 09:04:01 comeon CRON[18123]: (root) CMD (/usr/bin/unison &> /dev/null) Dec 28 03:31:01 comeon CRON[18143]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done) Jan 1 09:05:01 comeon CRON[18143]: (getmail) CMD (/usr/local/bin/run-getmail.sh > /dev/null 2>> /dev/null) Jan 1 09:05:01 comeon CRON[18142]: (root) CMD (if [ -x /etc/munin/plugins/apt_all ]; then munin-run apt_all update 7200 12 >/dev/null; elif [ -x /etc/munin/plugins/apt ]; then munin-run apt update 7200 12 >/dev/null; fi) You can see a line dated from the past in the middle, but CRON id is well incremented the right way. I don't understand how it is possible ... Thanks for any track. Nicolas PS : One other thing is that cron.daily isn't run anymore (logwatch, logrotate, apt, etc ...) but searches points that date/time problems could lead into this. PS2 : date is well sync between the 2 servers: Code: date && ssh root@server2 'date' jeudi 1 janvier 2015, 10:13:25 (UTC+1100) jeudi 1 janvier 2015, 10:13:25 (UTC+1100)
