Hmmm,

on a Linux system - you can always create a definition for logrotate.
It might be tricki though if using dynamically created files. But if using a 
Database backend, and only the Alert file in /var/log/snort/alert to be 
rotated, the rule for logrotate would look like this on a Mandrake-9.1 
system:
# cat /etc/logrotate.d/snortd 
/var/log/snort/alert {
        sharedscripts
        rotate 5
        weekly
        postrotate
        /usr/bin/killall -HUP snortd #
        endscript
}

I Don't know if restarting the entire application is better or not - however - 
I think it should work :) Just testing it now.

Cheers

        Joerg

Yes, I think you can. Anyone please correct if I am wrong. You can limit
file size by using unified output plugin.

Close, but not quite.  He wanted files to be rotated every time they
reached a certain size.  Unified doesn't do that.  The limit is the max
size of the file.  Once the size is reached, the file pointer wraps around
and starts filling up again from the 'front' of the file.  I think I've
heard things like that referred to as a 'circular file'.

Cheers!
