Brian, thanks for correcting me. The reason is that my sites all have a 500megs limit, and therefore all log max sizes were
50megs....

Are you sure that the logs are ONLY rotated if they reach a certain size? AFAIK they are rotated (1) if they reach a certain size
and (2) weekly, no matter how large they are.

/etc/cron.daily/logrotate is, of course, executed every 24 hours with /etc/logrotate.conf as configuration file. If you have a look
at exactly this /etc/logrotate.conf then you'll know what I mean (with (2)).

Yes, this would be the case if logrotate.conf wouldn't tell logrotate to do it's job weekly no matter what size the files have
reached.....

No good, no no, because of two reasons:
(1) Imagine the log file size growing over the user's disk space quota? hmm.....
(2) More work. For every virtual site you create you will have to modify the respective /etc/logrotate.d/siteX file....., and nobody
knows when and why the GUI would want to restore the default sizeX file. But I don't think it restores ALL siteX files everytime you
create a new virtual site.....; I guess it only restores the default siteX file if you modify the respective virtual siteX.

Better solution would be, though I don't know if this will work......
(1) Leave the logfile size limits as they are to ensure that they will never exceed user's quota.....
(2) Now you can either move /etc/cron.daily/logrotate to /etc/cron.monthly/logrotate, so that logrotate itself will only be executed
once a month (not good because then the logfiles can still fill / eat up :-) the user's assigned webspace)....., OR leave logrotate
where it is (at /etc/cron.daily/logrotate) and change its configuration file (/etc/logrotate.conf). There just change the line where
it says "weekly" to "monthly".

Again, don't know if this will work..., but I'll make it so. ;-)
