Macintosh HD slowly dropping to 0 for no reason

Earlier today I deleted a few files and check my HD to see that I had around 35 GB free on my 80 GB SSD (Macbook Pro). I was now just browsing the internet and checking my e-mail when a notice popped up and said that I had less than 250 MB of space left and needed to delete files. I opened up Finder to see it quickly dropping and I restarted my computer when it hit 50 MB free. When it restarted it said there were 800 MB free and now has jumped back up to around 22 GB, but it is slowly dropping again. I used Disk Inventory X and couldn't find anything out of place, I have no idea where the space is going and what is causing this. I am worried that I have a defective SSD, any ideas?

EDIT: Okay I seem to have found what is taking up all of the space (26 GB worth of .asl log files), but I can't figure out what was causing this. Here is one of the log file's output:

That looks like disk errors. You can probably delete all but the most recent ASL log files (keeping the most recent one so you can find the problem).

Try booting from your install CD and running disk utility repair.
