Heroku Python应用程序突然出现R15错误

我正在使用免费的heroku dynos和postgres，运行python flask应用程序。它经常在免费dynos的内存限制上关闭它（该应用程序在启动时会加载一些型号），但在八个月的时间里，它运行没有问题。然后今天，我看到了这个错误：

我得到了R15错误，但它似乎没有达到自由动态的两倍极限。heroku或python中是否有什么变化会突然影响我的应用程序的加载方式

---

如有任何需要调查的建议，将不胜感激

我也遇到了同样的问题-我的应用程序使用免费的dynos运行了几个月，在180%的内存使用率下没有问题，但从2天前开始就失败了：

Process running mem=512M(100.0%)
Error R15 (Memory quota vastly exceeded)
Stopping process with SIGKILL

---

我希望这可能是相关的，但不幸的是他们已经关闭了它。

这似乎是Heroku的一个问题，现在需要解决。我已经给Heroku发了一张票，昨天收到了以下回复：

看起来这与我们的工程团队正在进行的新基础设施展示有关。他们最近进行了修复，以正确计算R15错误，这样您就不会遇到任何其他问题。对于由此造成的不便，我们深表歉意，如果您有任何问题，请告知我们

我确认我的应用程序至少运行正常。希望你也一样
