I have a Mac Mini running 10.8.2 that has mysteriously run out of space. It is VERY BAD as it is the main audio playback computer at the theater I work at. It runs QLab, and that's it. A week ago it said "your startup disk is almost full". Now it is full, finder just stopped working altogether, making it impossible to run disk utility, etc. I read all of the articles about the aslmanager and such, which prompted me to download Disk Inventory X. On a year-old carbon copy clone of the aforementioned Mac Mini, I found that there was a file taking up 59GB (!) of space. It is the private/var/log/system.log file. I inspected the system.log file in Console and I got this message over and over and over again: (date) (time) localhost coreaudiod: (date) (time) [AirPlay] ### Write request (2048, 2048 bytes) when player not fully started I can watch as it does this every few seconds and watch my free space tick away. I googled the error and found that it is an issue with QLab, and am in the process of finding out how to get it to stop, but in the meantime, I think I will have to delete the system.log file since it takes up so much space. Can I do that?? Please help! I am running off of a backup machine that is likely to have this happen to it, too, as it is nearly identical.
