Ubuntu has a separate file /etc/logrotate.d/exim4-paniclog
which says:

/var/log/exim4/paniclog {
         size 10M
         missingok
         rotate 10
         compress
         delaycompress
         notifempty
         nocreate
}


I have completely rewritten mine to:

/var/log/exim4/paniclog {
      # keep for a long time, but don't let them be world-readable!
      daily
      dateext
      rotate 600
      create 0640 Debian-exim Debian-exim
      sharedscripts
}


The "sharedscripts" entry may be significant -
I have also added it to my /etc/logrotate.d/exim4-base
However there are no exim postrotate scripts, so it may
not matter.

I don't see the point in compressing a file which should be empty
(it gets bigger *and* harder to read).
I rotate daily so that new panics can be told instantly from old ones
(and maybe to be consistent with the other exim logs).

We are suspicious that this *is* a *subtle* logrotate issue.
