--- Comment #2 from Ken Sharp imwellcushtymelike@gmail.com --- It's the default. :-D http://www.bugzilla.org/docs/2.22/html/configuration.html
The low limit is a good idea, but some logs can span two or three compressed volumes and with certain kinds of bugs you can't be certain that the first or last 100,000 lines (for example) are any use: the only thing to do is to check a full log.
If it hits four split volumes I usually give up anyway - the log is simply labelled "too big".
