我们有多个应用程序服务器，并且我们的订单有时会因OCAException而失败。问题在于，从外部系统更新产品数量（自定义属性）是我们订单工作流程的一部分，并且有时（并非总是）发生此异常。我已经在intershop ORMException could not update - refresh ORMObject处看到了讨论，所以我在这里知道问题-更新其他线程和/或应用程序服务器中的对象。 但是我不明白为什么即使在我们的测试实例中，当更新数量作业正在运行时，例如在上午6点，什么也没有发生的情况下发生此异常-没有其他作业正在运行，没有用户活动？
作业本身持续约7秒钟，并在一个事务处理流程中执行，该处理流程遍历WS响应对象，然后通过SKU从存储库中获取productBO，更新Quantity定制属性并基于该属性将产品设置为脱机或联机。
有人可以解释为什么会发生这种情况以及如何避免/解决它吗？
感谢进阶！

又一次更新，当系统作业“ ProcessProductNotification-TriggerNotificationFromJob”运行并尝试更新DomainPO对象时，也会发生相同的异常：
