At 6:25 this morning, this happened. Anyone have any idea of what's going on?

How can I run out of memory? My swap file is large enough and not being used to the max.

Also, typo on 1st line.

Then, later on, I get a bunch of these kinds of messages. This comes up periodically.

Later, I rebooted using the GUI. But it appears the post-mount did not run.
