Identifying a particular script

Hi, I'm creating an fps game...using UFPS.

the problem i'm facing here is, if a player jumps on some moving gameobjects, somewhere from my scripts the player gets an addforce and he just fly away .The worst part is i couldn't figure out from which script this is happening and it happens only on rare occasions.

is there any way where i can find this problem occurs and see if could get it when the player reaches some particular height.
