我正在尝试 wso2bam-2.4.0 部分分布式集群，因此按照说明尝试创建远程注册表。
当服务器启动时，我看到“无法激活注册表核心包”，因为
错误 {org.wso2.carbon.registry.core.dataaccess.TransactionManager} - 无法关闭交易。java.sql.SQLException：可用连接总数小于关闭连接总数
我在全新的独立安装（使用 h2 db）上尝试了这些步骤，当我启用远程注册表时发生同样的错误
<remoteInstance url="https://localhost:9443/registry">
<id>registryInstance</id>
<dbConfig>wso2registry</dbConfig>
<readOnly>false</readOnly>
<registryRoot>/</registryRoot>
</remoteInstance>
<mount path="/_system/config" overwrite="true">
<instanceId>registryInstance</instanceId>
<targetPath>/_system/config</targetPath>
</mount>
<mount path="/_system/governance" overwrite="true">
<instanceId>registryInstance</instanceId>
<targetPath>/_system/governance</targetPath>
</mount>
这是我证明有用的堆栈跟踪片段
