These settings have been in place for more than 6 months.

I considered the same situation the the size setting was an issue, and setup a test.

I created an entry called /etc/logrotate.d/testfrank to process a rotation on file /tmp/local0notices but with the same size and rotate settings otherwise:


Quote:
/tmp/local0notices {
missingok
daily
rotate 12
size 50M
compress
delaycompress
notifempty
create 640 root adm
sharedscripts
postrotate
/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
/bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true
endscript
}
and then I ran this short script, which creates 20 60M files in /tmp of the same name 'local0notices' and runs logrotate on them ...

Code:
for x in 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 ; do
  dd if=/dev/zero of=/tmp/local0notices bs=1024 count=60000
  ls -lh /tmp/local0notices
  /usr/sbin/logrotate -v /etc/logrotate.conf 
  ls -altr /tmp/local0notices*
done

the result of which is good, I see 12 files in /tmp ...

-rw-r----- 1 root adm 59657 Mar 12 13:03 /tmp/local0notices.2.gz
-rw-r----- 1 root adm 61440000 Mar 12 13:03 /tmp/local0notices.1
-rw-r----- 1 root adm 0 Mar 12 13:03 /tmp/local0notices
The test works fine.

What looks weird to me on the real files, besides there's only ever 4 versions when I am trying to maintain 12, is the size of the files. It looks suspicious like another configuration setting may be processing the files before they're reaching 50M, the 433045 should be 50M or more.
I'm also not sure about the file name ending with .0 My test script didn't create a .0 file? ...:

Quote:
# ls -la /var/log/local0notices* | cat -n
1 -rw-r----- 1 syslog adm 342596 Mar 12 12:43 /var/log/local0notices
2 -rw-r----- 1 syslog adm 433045 Mar 6 21:16 /var/log/local0notices.0

4 -rw-r----- 1 syslog adm 42670 Feb 20 21:07 /var/log/local0notices.2.gz
5 -rw-r----- 1 syslog adm 35328 Feb 13 21:18 /var/log/local0notices.3.gz

strclean

strclean(8)						      System Manager's Manual						       strclean(8)

NAME

       strclean - Removes outdated STREAMS error log files

SYNOPSIS

       /usr/sbin/strclean [-d logdir] [-a age]

FLAGS

       Specifies  a  maximum  age  in  days for the STREAMS error log files if this not the default age of 3.  The value of age must be an integer
       greater than or less than 3.  Specifies a directory for the location of the STREAMS error log files to  be  removed  if	this  is  not  the
       default directory /var/adm/streams.

DESCRIPTION

       The  strclean  command cleans the STREAMS error logger directory of log files (error.mm-dd) that contain error messages sent by the STREAMS
       log driver (strlog).  If no other directory is specified (the logdir argument), the command removes error log files in the /var/adm/streams
       directory.  If no other age is specified (the age argument), the command removes error log files that have not been modified in 3 days.

       The strclean command is executed by the cron daemon on a periodic basis.

EXAMPLES

       To remove the day-old error log files from a directory called /tmp/streams, enter: strclean -d /tmp/streams -a 1

FILES

       One or more error log file or files on which strclean operates.	The mm.dd in the filename indicates the month and day of the messages con-
       tained in the file.

RELATED INFORMATION
