Logrotate, by default, runs daily (not hourly) and renames the log files that it rotates by appending to them the current date. In your case, you are running it hourly, so it only runs successfully only once a day. The second time that it will attempt to run in the same day, it will find that there already exists a rotated file with the appended date for that same day, and fail.
So, either run it daily, or change the renaming scheme.

Hi all,
I have a problem with logrotate and I don't know why. In /var/log/messages appears these errors:
Apr 8 15:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 16:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 17:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 18:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 19:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 20:01:02 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 21:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 22:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1] Apr 8 23:01:01 plzfnsm02 logrotate: ALERT exited abnormally with [1]
It seems the problem if with this logrotate.conf (executed every hour):
create dateext
/srv/www2/logs/viewer.log { size 512k create 0640 www www missingok rotate 7 compress delaycompress copytruncate notifempty }
Doing a debug:
[root@www02 ~]# logrotate /data/config/etc/logrotate.conf -dv reading config file /data/config/etc/logrotate.conf reading config info for /nsm/moloch/logs/viewer.log
Handling 1 logs
rotating pattern: /srv/www2/logs/viewer.log 524288 bytes (7 rotations) empty log files are not rotated, old logs are removed considering log /srv/www2/logs/viewer.log log needs rotating rotating log /srv/www2/logs/viewer.log, log->rotateCount is 7 dateext suffix '-20140409' glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' glob finding logs to compress failed destination /srv/www2/logs/viewer.log-20140409 already exists, skipping rotation
According to this kb from redhat's website:
https://access.redhat.com/site/solutions/39006
problem could be selinux. But SElinux is disabled:
[root@www02 ~]# sestatus SELinux status: disabled [root@www02 ~]#
Any idea?? Could be a bug??
Host is a CentOS 6.5 x86_64 fully patched.
