S2 - 测试网络延迟。网络恢复正常后，节点无法进入共识状态。重启所有节点后仍然有问题。

[foreso-GitHub]

测试网络延迟。网络恢复正常后，短时间内会生成大量区块（可能是前面积压的区块），但随后所有节点的区块高度不会增加（此时log中显示的共识状态true true true true - 5 5 5 4）。重启后也无法恢复共识（true true true true - 5 5 5 3）。再次重启，3个节点进入共识状态、区块增加，另外两个节点区块不增加，但log显示共识正常（true true true true - 5 5 5 5）。

20200915更新版本，断网测试后很容易发生区块不再上升的情况。 从log看，共识是在进行的。

测试网络延迟。网络恢复正常后，短时间内会生成大量区块（可能是前面积压的区块），但随后所有节点的区块高度不会增加

20201027版本上，多次尝试后，该问题仍然可以重现。

[foreso-GitHub]

版本：20201114-v0.5.2-dev，执行网络错误注入测试（损坏、乱序、延时等）+节点断网后，仍然会发生全网节点共识停止。

[foreso-GitHub]

版本：20201130-v0.5.3-dev已经修复。
