I'm not sure about corrupt, but I won't rule it out. I'm not sure
because `cat`, `tail`, and some other utilities seem to work correctly
(but maybe they're more forgiving?). Thanks for the suggestion!

You're absolutely right - bad copy'pasta on my part; that should read:
`/vhosts/archivesspace/logs/archivesspace.out {`

/vhosts/archivesspace/logs% ls 
archivesspace.out              archivesspace.out-20210611.gz 
archivesspace.out-20210613.gz  archivesspace.out-20210615.gz
archivesspace.out-20210610.gz  archivesspace.out-20210612.gz 
archivesspace.out-20210614.gz  archivesspace.out-20210616.gz

We're good here (we use the datext in our logrotate.conf), and zgrep
(thank you for the reminder!) works fine on the *.gz files. 

The `aspace-log.out` is a copy of log from pre-logrotate, with a
different name (i.e. `cp archivesspace.out ~/aspace-out.log`).

Sadly this doesn't seem to provide any new information:


% logrotate -dv /etc/logrotate.d/archivesspace
reading config file /etc/logrotate.d/archivesspace
Allocating hash table for state file, size 15360 B

Handling 1 logs

rotating pattern: /vhosts/archivesspace/logs/archivesspace.out  after 1
days (7 rotations)
empty log files are not rotated, old logs are removed
considering log /vhosts/archivesspace/logs/archivesspace.out
  log does not need rotating (log has been rotated at 2021-6-16 3:45,
that is not day ago yet)
