I've installed a lot of Zope instances on my laptop since version 2.7.3 and out of curiosity and desperate need for more hard drive space I thought I'd log rotate them all with the standard Linux
Before doing the log rotate, the total size of all my
event.log files came to about 290Mb! After running
logrotate (twice of course to go from event.log.1 to event.log.2.gz) the total size become 20Mb. Not a huge significance in the world of gigabyte hard drives but at least something.
