java.lang.OutOfMemoryError与不和谐JDA 350线程

Question

所以我会尽力解释我的问题。目前，我正在进行一项规模相当可观的计划。然而，正如350所说，我从未使用过这么多线程。它目前给了我一个内存不足的错误，但我已经尝试了多种选择：

• 添加-Xss参数
• 添加我可以在这个网站上找到的其他参数
• 此外，我还尝试编辑堆栈大小和用户限制

下面列出了内存溢出问题的错误。

当我发现无论我做什么，线程堆栈大小总是看起来是1024。

我目前从具有以下规格的VPS运行此. jar文件：

• 无限制流量

我的问题是，有没有办法编辑这个线程堆栈大小？

另一个单独的问题：每当我使用-Xss2g时，它确实会显示它超出了限制，但是有没有办法编辑这个限制？

Answer 1

我实际上设法弄清楚了。

我托管的提供商将我可以同时运行的线程数量限制为1300个线程。因为他们有固定的数量，所以我的线程一直遇到问题，错误也显示在问题中。

因为他们锁定了这个金额，我的选择受到限制，所以我决定换一个提供商。

Answer 2

您可以尝试配置JDA并更改默认值以减少内存占用。确保您也使用最新版本的JDA（目前为4.2.0_252）。
