Network freeze out of clusters

I am using RTEMS 4.5.0. There is some problem with the IP task. If I pump enough data
at the card I end up getting "Still waiting for an mbuf cluster" message. The only way
out is a reboot.
I am NOT running any appplication task which opens or closes sockets. I am pumping
data by ping or by sending TCP connect request(which are rejected since there is no
application listening on that TCP socket).
Has anyone seen similar problems? I am aware of the network freeze problem caused by
improper handling of sockets by application tasks. This is a different problem.
Any insights will be helpful.
