我们正在本地运行Artifactory 7.5.5，在CI中执行计划的日常任务（

npm安装

）时会出现此错误

最后它说：

org.artifactory.storage.StorageException-未能更新唯一索引表

，原因是

org.postgresql.util.psqleexception:FATAL:抱歉，已经有太多客户端

然后，CI作业将退出

有人能帮忙吗？

此错误表示PostgreSQL数据库的数据库连接已用完。

我建议您根据可用的公式增加DB端允许的DB连接。

嘿，Ariel，谢谢您的帮助。您是指此设置并将

300

设置得更高吗

yml artifactory:database:maxOpenConnections:300

或

access

和

meta

设置？@SvenWagner nope。这些配置Artifactory可以打开多少连接。您应该在DB端修改它可以接受的连接数。可能会有帮助：嘿，艾瑞尔，谢谢你的帮助。您是指此设置并将
