System.out.println是否可能是java应用程序挂起的原因？

我使用SpringBoot开发了一个过程，大约需要7个小时才能完成。 出于调试目的，初始版本有很多“System.out.println”调用。 当我在eclipse上运行这个过程时，它一直运行到最后，没有任何问题。 但是，如果我直接在终端、本地或云虚拟机上运行它，两三个小时后，应用程序就会停止。进程保持活动状态，但调试消息停止，处理也停止

是否有可能这些消息以某种方式崩溃，或者在一段时间后阻塞了我的进程

如果是真的，我只能想象eclipse有一些机制来丢弃旧的控制台消息，一旦它有一个控制台缓冲区最大大小的配置，这将阻止应用程序停止

谢谢

根据JimN的建议，关于从线程中提取信息，以下是我的发现：
