Every week, I seem to be getting the following two Cron messages:
/etc/cron.daily/logrotate:
gzip: stdin: file size changed while zipping

/etc/cron.daily/spamassassin:
channel: no 'mirrors.updates.spamassassin.org' record found, channel failed
sa-update failed for unknown reasons

Not sure what's causing these.

Exactly what the messages say.

In the first case something was writing to the file being archived while the archiving was taking place.

In the second case, Spam Assassin was unable to access the mirror it needed to update itself.

Thanks for the reply. I haven't made any custom changes to the cron.daily directory or logrotate. So, would this be a bug in Debian? –  Ash Aug 12 '13 at 7:41
    
Not sure if you would class it as a bug in Debian (don't want to go there anyway, but see lists.debian.org/debian-user/2012/07/msg01955.html). You can "work around this issue by modifying the scripts in /etc/logrotate.d and removing the "compress", or possibly by adding the "delaycompress" option. –  davidgo Aug 12 '13 at 18:19
    
To look at the spamassassin problem can you provide the output of sa-update and also what happens if you ping mirrors.updates.spamassassin.org –  davidgo Aug 12 '13 at 18:19
    
sa-update does not give me any messages. The ping fails with an 'unknown host' message. –  Ash Aug 13 '13 at 1:10
    
I'll add 'delaycompress' and let you know if it helps. –  Ash Aug 13 '13 at 8:33
