给producer111a投票以后，我一直在监控几个日志平台，发现不知什么时候，00-eosio节点已经不出块了，开始接受块，而01-producer111a节点显示开始出块，其他候选人仍旧接受块。这时候我更换策略，开始用股权账户为producer111b投票，投完以后，没过多久，让我捕捉到01-producer111a节点的日志和producer111b节点的日志变化了。
01-producer111a节点的日志：

01-producer111a节点由produce_block，经历start_block以后，改为on_incoming_block。
02-producer111b节点由on_incoming_block，经历start_block以后，改为produce_block。
那么这个start_block事件的内容在两个节点里报出来的都是相同的内容：
promoting proposed schedule (set in block 2683) to pending; current block: 2684 lib: 2683 schedule: {"version":2,"producers":[{"producer_name":"producer111a","block_signing_key":"EOS8imf2TDq6FKtLZ8mvXPWcd6EF2rQwo8zKdLNzsbU9EiMSt9Lwz"},{"producer_name":"producer111b","block_signing_key":"EOS7Ef4kuyTbXbtSPP5Bgethvo6pbitpuEz2RMWhXb8LXxEgcR7MC"}]}意思就是producer111b晋升为出块节点。接着我们再继续观察日志，会发现：
producer111a和producer111b是交替出块，producer111a节点并没有因为producer111b的晋升而不再出块。
producer111c没有人给他投票，所以继续接收。
