Well, disable it temporarily and see if the problem goes away...

If you set up queueing, and the queue you assign ICMP to is full, what
do you expect happens when ping tries to send an ICMP echo request?

Have you checked the run-time statistics of the queues (pfctl -vvsq),
any correlation between drops and ping error messages?
