Could you put the entire message here? Destroying a peer generally occurs for various reasons, including hold time expired, changing a summary, a stuck in active route, etc. If you're seeing no cause in the output, check the _other_ router, the one that was reset, to see if you can find a cause on that side. One side will always see the reason for the reset, the other side will always just see a reset by the neighbor.
