I took a picture with lens cap on and 30 seconds and there are a lot of red,white and blue dots it only happens when i shot long exposures but does it a big problem?

It's not unusual for a long exposure.
FWIW, these are not stuck at maximum value; simply over-active.

Black images aren't a good choice to test for "hot" pixels.

If you see problems in any of your normal photography then it's worth looking into.
I can help you perform a reasonable test.
Contact me by email or Private Message (PM) if you'd like that.
