What is ikeTunHistInP2ExchgInvalids?

Total Phase-2 exchanges that were received and found to be invalid by this Phase-1 IKE tunnel, kept in the history table after the tunnel ended (the value no longer changes). Invalid exchanges usually mean malformed messages or incompatible peer behaviour; a non-zero, growing value is worth a look at both peers' IPsec configuration.
