For example:
9/4/10 1:48:31 PM KernelEventAgent[72] tid 00000000 received event(s) VQ_LOWDISK, VQ_VERYLOWDISK (516)
This indicates that Mac OS X has detected a drive (hard drive, RAM drive, Zip Drive, etc), that is very low or out of disk space. Â If this is your boot drive, you will receive a POP up warning message that the disk is out of disk space.
How to fix this? Â Free some disk space up from the drive in question, burn files to DVD, Delete unnecessary files or move them to a external drive.
