根因分析

一个goroutine持有互斥锁并等待另一个也需要该锁的goroutine，导致死锁。

English

A goroutine holds a mutex and waits for another goroutine that also needs the same mutex, causing a deadlock.

generic

解决方案

  1. 85% 成功率 
    Avoid holding mutexes while waiting for other resources. Use lock ordering or try-lock patterns.
  2. 80% 成功率 
    Use context.WithTimeout to break deadlocks by aborting the operation.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Sleep does not resolve the deadlock; the other goroutine is also blocked.

  2. 80% 失败

    The deadlock is due to mutex, not channel; buffering does not help.

  3. 70% 失败

    This introduces data races and may corrupt data.
