Also, during back warming you might get coke in you blowdown drum, coke condesate drum and or backwarming strainers, depending on your set up.
I would look first into your cutting procedure. Check for time (cutting too fast?), upper dome cleaning (some systems have a cleanout mode), sound of water against the drum wall and color of water during cleanout.
