As you can see, logrotate aborts and the file is not rotated.  I assumed the problem was with the missingok option so I tested this possiblity as shown below.

touch test.log.0 test.log.1 test.log.2 test.log.3

ls -l test.log*
-rw------- 1 root root 1104925 Oct 23 16:16 test.log
-rw------- 1 root root       0 Oct 23 17:37 test.log.0

-rw------- 1 root root       0 Oct 23 17:37 test.log.2

No error but the file has not been rotated.
Anyone have ideas on what may be wrong.  The last time my logs were rotated was April.

Re: [Solved] Logrotate not working

Are you running logrotate as root?  Usually, it is run as a cron job with root permissions.

Re: [Solved] Logrotate not working

I noticed last night that the logs have not been rotated.  For the moment, I am testing as root.  It normally runs as a cron job.

Re: [Solved] Logrotate not working

It seems my state file (/var/lib/logrotate.status) was corrupted.  I deleted this file and then did "logrotate -f /etc/logrotate.d/syslog-ng".  The state file was recreated and now everything is working again.  No idea how the file became corrupted, though.
