An IKE negotiation failed because the server cannot build the transform header for the specified protocol. This error is due to either the transform header being empty or a memory allocation failure.

Additional diagnostic messages that have the same message instance number will be issued to identify the impacted Security Association (SA). The message instance number precedes the message number in the log output and is used to group related messages from the IKE daemon.

transform_id is the value used to identify this transform in an IKE proposal. Supported transforms for IKE SAs are described in Policy Agent and policy applications in z/OS Communications Server: IP Configuration Reference. Phase 1 transforms are specified on a KeyExchangeOffer statement, and phase 2 transforms are specified on an IpDataOffer statement. Phase 2 transforms specify the encapsulation mode on the HowToExcap statement.

protocol is a string representing the protocol. protocol is either AH, ESP, or OAKLEY.
