Hello,
I have this problem too. On most every login I have the same symptoms : Red screen, Hurt, scream, etc... regardless of if my inventory is full or not.
I understand now why my pants statut's pristine decrease or get ruined a lot of time was guessing it was Zeds hitting me.
In some French forums i've seen a lot of people reporting that they got broken legs straight out on logging in... Broken legs and so ruined pants and ruined items in it. Look like the same problem.
