Infill bumps up and shakes print bed mid way through print

[RussellCreations 0]

I've been printing for at least a year and a half and have been coming across this issue as of recent.  For my longer prints the infill will "bump" up at certain location and cause the print to be uneven, which will intern shake the printbed something fierce. I'm wondering if anyone else has had this issue and if anyone has resolved it.  Any help would be appreciated, thanks!  I've attached some pictures and will list off my settings from Cura (computer says 15.04.3). I'm using an Ultimaker 2 Extended.
