cloudfoundry 上的 PostgreSQL 抛出 PSQLException : FATAL: terminating connection due to administrator command

Question

我有一个在 cloudfoundry 中成功运行的 grails 应用程序，使用 H2 作为数据库。我现在想切换到 postgresql。当我针对 postgreSQL 在本地运行应用程序时，一切都按预期工作。

在 cloudfoundry 实例上，我在一个相当长时间运行的分析中遇到异常，我将其作为后台任务执行(使用 grails 执行程序插件)。在这个异步任务中

def future = executorService.submit({
    return analysisService.analyzeProject(model, project)
})

我从数据库中得到以下异常:

有什么可能导致这种情况的想法吗？

Answer 1

您很可能会为长时间运行的连接达到配置的超时(如果我没记错的话无法更改，因为它是为了保护服务器免受格式错误的查询的影响，这些查询会消耗所有 cpu/io)

您可能想尝试将长时间运行的查询分割成更小的查询并对结果求和(如果是选择)
