Question

我正在Linux（特别是Ubuntu LTS 18.04）的后台运行R程序。当程序遇到问题时，它会生成无限数量的错误消息，也就是说，它会继续生成错误消息，直到我手动终止该进程为止。

下面显示的错误消息摘自一个5.5 MB的日志文件，该文件几乎完全由相同的重复错误消息填充。如果我无法终止该进程，则日志文件可能最终会耗尽整个硬盘驱动器。

我感觉这更多的是Linux问题而不是R问题，因为我已经在Windows上的R中开发了多年，却从未见过这样的事情。我是刚开始在Linux上使用R进行开发的新手，在很短的时间内，我反复遇到无限的错误消息。

如何防止生成无限错误消息？同时，我确实希望收到FIRST错误消息，以便对可能的问题有一个线索。

错误消息示例：

Error: cannot allocate vector of size 12.4 Mb
