根因分析
由于通道操作阻塞或无限循环而永不退出的 goroutine 会导致内存泄漏。
English
Goroutines that never exit due to blocked channel operations or infinite loops leak memory.

无效尝试
常见但无效的做法:
-
100% 失败
GC doesn't collect goroutines; they are not garbage.
-
90% 失败
Temporary mitigation; eventually memory exhausts.
-
80% 失败
Leaks accumulate, causing OOM crashes.
