<--- Last few GCs ---> 什么意思

"Last few GCs" 可能是指最近几次垃圾回收（GC，Garbage Collection）。在计算机科学中，垃圾回收是一种自动内存管理机制，用于释放不再使用的内存空间。在某些编程语言中，垃圾回收机制会周期性地扫描内存，找出不再使用的对象，然后将其释放，以避免内存泄漏和程序崩溃。 "Last few GCs" 可能用于描述最近几次垃圾回收的情况，以便优化内存管理和程序性能。

As an AI language model, I do not have access to a specific system's GC logs. However, in general, garbage collection (GC) is a process used by many programming languages to automatically free up memory that is no longer used or needed by an application. The frequency and duration of GC events can vary depending on the language and implementation being used, as well as the amount of memory being allocated and released by the program. In some cases, developers may need to adjust certain settings or algorithms related to GC to optimize performance and memory usage.

这是一个 JavaScript heap out of memory 错误，常见于 Node.js 应用程序中。它表示 Node.js 的内存使用超过了可用的堆内存限制，导致应用程序崩溃。通常需要增加 Node.js 堆内存限制或优化代码以减少内存使用。在这个例子中，是一个 Vue.js 应用程序使用了过多的内存，可能需要检查代码并进行优化。
