I suppose you are using rte_ring as IPC mechanism between multiple processes, correct?
In theory - yes, if your producer crashed during enqueue() to the ring, then yes, the ring might be affected.
If producer already moved prod.head  and crashed before updating prod.tail, then no other producers
will be able to enqueue() into the ring, till you'll do reset() for it.
I expect such situation really rare and hard to reproduce, but in theory it is possible.
