Hi,
Yes, you can erase that file, it's just an old log. Just drag it to the Trash and empty the Trash.
However, it's a bit troubling that your console.log grew so large. That file is where the computer sends information. Usually, it's fairly small amounts of information, but sometimes a program will go crazy and spew huge amounts of information in there and fill up the hard drive.
You can open up that log in the Console application from your Utilities folder, but that might take a long time to complete for a log that huge. Better might be to open up the Terminal application from your Utilities folder and type this at the prompt, followed by the "enter" key:
tail -n 20 /Library/Logs/Console/501/console.log.1
I have "501" on my system instead of a username in the path. See if there are messages there that repeat a couple of times a second or so. That will print out the last 20 lines of that log.
Make sure that whatever filled up that log isn't still doing it. Note that the usual daily, weekly, or monthly maintenance scripts
don't rotate this log. The only time the console.log gets rotated is when you restart the computer. When you restart, the old one gets renamed to "console.log.0", "console.log.0" gets renamed to "console.log.1", etc., and a new "console.log" gets created. You should definitely
not delete the current one, by the way, as the system is still using it. And if the other ones are small you might as well keep them, they can be useful to look at later.
I have 11 in that folder on my computer dating back to when I first got it in November. The largest is 264KB. The current one is 32KB and my laptop has an uptime of 19 days.
