if this is for 7.1.1, then the size is actually the size that the log file gets saved off and a NEW log starts.

the field "Maximum Number of Archived Logs" is how many there will be. ie: if 4 then up to 4 logs are saved before rotate/overwrite

so for you guys interested in space, you'll need to know that your log(s) will accumulate over time.

log1, log2, log3 etc etc. it's up to you to grab the old ones and save them to HDD, if you are afraid of space issues. (btw, 'logx' is just for example- i forget the actual log file names)

a value of 0 prolly means just keep on going, vs non-zero means stop at x and start rotating.

i could be wrong about 0 though.
