请问LearnMaster方法中，下面这段逻辑什么情况下会成立？ if (oMasterOper.lastversion() != 0 && llInstanceID > m_llMasterVersion && oMasterOper.lastversion() != m_llMasterVersion) { BP->GetMasterBP()->MasterSMInconsistent(); PLG1Err("other last version %lu not same to my last version %lu, instanceid %lu", oMasterOper.lastversion(), m_llMasterVersion, llInstanceID);

    PLG1Err("try to fix, set my master version %lu as other last version %lu, instanceid %lu",
            m_llMasterVersion, oMasterOper.lastversion(), llInstanceID);
    m_llMasterVersion = oMasterOper.lastversion();
}
