+1. Also, adding 1/2 a crushed whirlfloc tab @ 10 min left in the boil then allowing the kettle gunk to settle 15-20 min before transfer to the fermenter will help avoid this.
Cold conditioning over time will also help to clear some chill haze, so you may see an improvement if the keg doesn't get consumed quickly.
