I think it will be corruption of a list rather than running out of a resource.  
Can you check the code in your driver that handles pbufs to make sure it 
correctly iterates pbuf->next as that is a common cause of problems.  Otherwise 
it could be a locking issue that is corrupting the list and only shows itself 
when the timing is right (or wrong, depending on your point of view)
