* Some of the reasons may include:
* HTLC Timeouts
- * Expected MPP amount to claim does not equal HTLC total
- * Claimable amount does not match expected amount
+ * Excess HTLCs for a payment that we have already fully received, over-paying for the
+ * payment,
+ * The counterparty node modified the HTLC in transit,
+ * A probing attack where an intermediary node is trying to detect if we are the ultimate
+ * recipient for a payment.
