Title:
  Laptop locks up once all memory used and encrypted swap in use

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Present state:

  KiB Mem:   3936908 total,  3737952 used,   198956 free,    12312 buffers
  KiB Swap:  4194300 total,   862544 used,  3331756 free,  1215956 cached

  If, for instance, more chrome tabs are opened, the pointer stutters
  and eventually the laptop locks up.  Encrypted swap is 4gb in size and
  on an SSD.  The UI is unusable.  The easiest recovery is to switch to
  a VT and kill a process.

  Swapon -s gives:

  Filename				Type	Size			Used	Priority
  /mnt/4096.swap                   file		4194300	862192	-1
