This event indicates that an error occurred while transmitting an IPMI message in the BMC2HOST direction. The data field contains more detailed information about the source of the error. Data Bytes 0 & 1 form a 16-bit IPMI error indicator that has the following values and meanings: 1 - IPMI_HOST_BUSY_TIMEOUT - The PDHC could not put a message in the BMC2HOST hardware message queue for over 10 seconds, so the pending message(s) were dropped. 2 - IPMI_INVALID_MSG_SIZE - The MP sent an IPMI message response that has an embedded size indicator that is less than 4 bytes or greater than the size of the message data. The poorly formed message response will be dropped. 3 - IPMI_BMC2HOST_Q_FULL - The BMC2HOST message queue in the PDHC is full, so a message response from the MP has been dropped.
