高输入发送率的Hyperledger Fabric SimulateProposite错误

方安怡
2023-03-14
    null

8 GB RAM DDR4

Ubuntu 19.04内核5.0.0-35-泛型

Docker版本19.03.4

docker-compose版本1.21.0

Peerer和orderer的Docker容器在1.4.3版本中使用Fabric映像，但我最近尝试了，结果是一样的。

我使用Hyperledger Caliper以高发送率对提案进行子化处理，其中一些提案被对等方接受（在执行过程中数量不同），但其他提案因以下错误而失败：

事务[901D0036B2]生命周期错误：

peer0.org1.com的建议响应错误：事务返回失败：未能提交任务进行处理

我在此报告具有错误的对等方日志：

正如消息信息1447所建议的那样，对等体未能为建议创建新任务，这可能是因为许多请求一起到达。这种考虑是否正确？有什么方法可以改变一个对等点可以创建的最大并行任务数吗？因为这种情况会发生，即使速度是100 rps，我认为我可以进一步推动性能。
