This may sound a bit ridiculous, but say the timer is every 0.25ms. 100kbit per 0.25ms = 400,000kbit or 400 mbit. It is remotely possible to hit a 300 mbit limit with only 100kbits of traffic, if the timer is sufficiently short, and your traffic is sufficiently bursty.
A cisco ping is not bursty, to the extent of hundreds of mb/s. Also, cisco ping doesn't offer 4,000 pings/sec.
Unless your traffic is Mcast, I doubt that issue is related.
Read on; EIGRP, CDP, etc.
Can you ask your provider how exactly they are limiting the pipe? When dealing with 300 or so megs, I doubt they will be shaping with a policy friendly to you, as the logistics of doing so are a bit difficult.
