Increased disk space after upgrade on domains

[Traged1]

Customers have reported that thier domains have jumped dramtically in disk space the night after the upgrade to PLESK 8.1.0. After reviewing thier accounts I have found that they all have very huge log files some of them over 500MB. I have removed these huge log.processed files so things should go back to normal for them. My question is, did this occur due to the fact that their log rotation was previously mal-functioning before the upgrade?

it is possible if they don't removed processed files

Actually I also noticed that several domain's log rotation have been disabled. I have to manually go through each of the 300 domains on this server and ensure that each domain's log rotation has been enabled.
