Hi I am using Centos 5.1 and I have a weird problem with squid logs
rotation. I have the file squid as follow in /etc/logrotate.d:

Recently I reduce size parameter.

/var/log/squid/access.log {
   weekly
   missingok
   rotate 10
   compress
   create 0660 squid squid
   missingok
   size 200M
   postrotate
     /usr/sbin/squid -k rotate
   endscript
}
/var/log/squid/cache.log {
   weekly
   rotate 5
   copytruncate
   compress
   notifempty
   missingok
}

/var/log/squid/store.log {
         missingok
         weekly
         compress
         size 200M
         create 0660 root squid
         rotate 4
# This script asks squid to rotate its logs on its own.
# Restarting squid is a long process and it is not worth
# doing it just to rotate logs
   postrotate
     /usr/sbin/squid -k rotate
   endscript
}


logrotate -vvv -f  /etc/logrotate.d/squid
reading config file /etc/logrotate.d/squid
reading config info for /var/log/squid/access.log
reading config info for /var/log/squid/cache.log
reading config info for /var/log/squid/store.log

The strange thing is that I get the following files:

[root at fido ~]# ls -lhtr /var/log/squid
total 409M
-rw-rw---- 1 root  root  323M May 26 04:21 store.log.4.gz

-rw-r----- 1 squid squid  359 Jul  8 10:45 cache.log.1.gz
-rw-r----- 1 squid squid    0 Jul  8 10:45 cache.log.0
-rw-r----- 1 squid squid 2.2M Jul  8 10:45 access.log.1.gz

-rw-r----- 1 squid squid 328K Jul  8 10:46 store.log
-rw-r----- 1 squid squid 957K Jul  8 10:46 access.log

I don't understand why compress old log files but doesn't delete old
non-compressed files uncompressed. Any ideas? (I've also modified
create parameter for squid be owner of access logs and run by hand
logrotate /etc/logrotate.d/squid to see if it repeats the case)

Thanks in advance
