It's been known to happen. Thinking specifically of the Battle of Long Tan.
My understanding from reading a number of accounts, and actually talking with a couple of the men who were on the ground, was that out of the 9 M60's, most had seized up by the end of it. This was due almost entirely because of the massively high rate of fire required to fend off the thousands (estimated at somewhere between 2,500 and 3,000) of Vietnamese coming in waves at the Company.
