It does, if so ordered from cron. Its log rotation is still not as
fully-features as logrotate, I believe.

Here's your problem: you're telling it to rotate
/var/log/asterisk/messages.1.gz etc. Quite funny actually, if it doesn't
happen on your system.

So you should:

A. edit this file to contain specific file names (or edit your
logger.conf config to have a suffing of .log to all the log files
there).

But even when you do that, next log rotates will take very long. If
you'll strace logrotate you'll then notice it tries to stat every file
it has rotated before.  This is because they are still listed in the
logrotate status file (/var/lib/logrotate/status on my system)

B. Edit the logrotate status file and delete all entries of bogus log
files. Probably something like: 

  sed -i -e '/\/var\/log\/asterisk/d' /var/lib/logrotate/status

(But the above is untested)

Hmm.. Just read this thread. This was my guess all along. This funny
thing happened to me before. Renaming the log files to *.log will also
simplify your logrotate file. Anyway, the Debian file has something of 
the sort of:

  /var/log/asterisk/cdr-csv/Master.csv /var/log/asterisk/debug /var/log/asterisk/event_log /var/log/asterisk/messages {

However here's something less obvious:

Even after you edit the logrotate config, next log rotates will take very 
long. If you'll strace logrotate you'll then notice it tries to stat 
every file it has rotated before.  This is because they are still listed 
in the logrotate status file (/var/lib/logrotate/status on my system)

Edit the logrotate status file and delete all entries of bogus log
files. Probably something like: 

  sed -i -e '/\/var\/log\/asterisk/d' /var/lib/logrotate/status
