swap_pager: I/O error vm_fault: pager read error (python2.7)

Got the following in my security run output:

kernel log messages:
> swap_pager: I/O error - pagein failed; blkno 5767214,size 32768, error 6
> vm_fault: pager read error, pid 3809 (python2.7)
> pid 3809 (python2.7), uid 0: exited on signal 11

Not sure what this means. Anybody have any ideas? I tried Googling and didn't have much luck. Looks like a problem with python2.7 but not sure what more than that this indicates nor the severity of these messages.

Thanks!

Hardware specs? Sytem build (from System -> Information)?

You had a read error reading something in from swap. This isn't too good, as it can kill things that need to be running. It also suggests you might not have enough RAM.
