php - "pcntl_fork(): Error 12"是什么意思？

Question

我找遍了，脸色铁青，找不到这个问题的答案。

在哪里可以找到列出 pcntl_fork() 的所有错误代码含义的表格？甚至 C fork() 函数，就此而言。

Answer 1

似乎 12 错误代码表明没有足够的内存进行 fork 。

参见 this post ，例如(引用):

I've had this when
(1) I've run out of memory, and
(2) when the pid table is full. In the latter case a rogue program was constantly forked child processes & not picking-up the message when they die. The result was >200 zombies.
