An equaliser from New Zealand striker Chris Wood added to an Andy King goal to deny Palace a first victory in seven matches after Danny Gabbidon and Stephen Dobbie had ended a barren run of five games without a goal.
"We're disappointed with that having been in front twice but it's important to have got a point," said Palace boss Holloway.
"I would have preferred two more but you've got to take what you can. I was impressed with the courage of the lads and we scored two goals, which we haven't done for a while.
"I'm just disappointed with the last goal because it looked like a mistake and we have to eradicate them. It's another point to our target and we now have to move on.
"We need to tweak the nose of fear and stick an ice cube down the vest of terror."
