I don't think it is caused by the system running low on memory. I saw this issue this morning on arale and the system has plenty of memory free:
total used free shared buffers cached
Mem: 1937952 1327364 610588 31468 11028 254584
-/+ buffers/cache: 1061752 876200
Swap: 524284 0 524284
There are these suspicious lines in .cache/upstart/unity8-dash.log
