Question

当我使用docker-compose启动Docker容器时，出现以下错误：

（该错误显示为partyb，但对于除公证人以外的所有节点都是相同的错误）。显然我的CorDapp太大了。

我在docker容器中阅读了Java上的一些articles，并尝试相应地对其进行配置，但到目前为止仍未成功。

我尝试访问Java选项 UseCGroupMemoryLimitForHeap ，并初始化了docker swarm以使用 resources 配置，但是没有成功。

这是撰写文件，没有任何配置：

在此先感谢您的帮助！

您的计算机有多少内存？ Corda在新版本中变得越来越渴望资源。您的计算机很可能没有足够的内存。

除非，docker可能会将可用内存限制在每个节点上。在node.conf中增加堆大小或增加堆大小可能会有所帮助-https://docs.corda.net/head/corda-configuration-file.html#overriding-values-from-node-conf。
