A #4 hook is not too big, IMHO. I use a #2 on 1/32 & 1/16oz jigheads (custom made). I've got some with a #4 hook, and I've caught Bluegill on them (when using 1.5" Panfish Assassins), but not when using 2" plastics (regardless of hook size). I get the "machine gun" hits, all the same.
My gut instincts say you're getting hits from Sunfish (pannies ??), rather than Crappie, unless the Crappie are very small. As has already been stated ... a single "tap" is normally a Crappie, whereas a series of "taps" is likely another species. You can simply downsize your jig & plastics, when this happens again, and possibly catch & identify the culprit. :twocents
