Hyperledger fabric Hyperledger Fabric v1.2-调用链码名称失败：“1”；qscc“，错误：执行事务时超时

我有3个虚拟机的结构网络设置，其中包含4个组织，每个组织有2个对等体，以及各自的CouchDB实例、1个专用CA和单个订购者。我使用Hyperledger Java SDK公开rest API供使用

我们在执行查询时经常遇到问题，无论是富文本查询，还是在下面提到的历史查询中。根据日志，我可以看到用户Chaincode已成功检索查询结果，但在执行“qscc”Chaincode调用时失败

我最近也遇到了这个问题。在检查了一些相关问题和文档后，我的临时解决方案是重新启动您在日志中发现

未能调用链码名称“qscc”

的对等方：

docker restart <peer container's id>

docker重启感谢您的详细解释！尽管Fabric 1.2.1中已告知对此进行修复
