根因分析

在当前协程未锁定的 sync.Mutex 上调用 Unlock，通常由于缺少 Lock 或重复 Unlock。

English

Calling Unlock on a sync.Mutex that is not locked by the current goroutine, often due to missing Lock or double Unlock.

generic

解决方案

  1. 99% 成功率 Always pair Lock with defer Unlock immediately 
    mu.Lock(); defer mu.Unlock(); // critical section
  2. 98% 成功率 Use sync.RWMutex with proper RLock/RUnlock pairing 
    mu.RLock(); defer mu.RUnlock(); // read section

无效尝试

常见但无效的做法:

  1. Adding defer mu.Unlock() without ensuring Lock is called 70% 失败

    If Lock panics, Unlock still called on unlocked mutex.

  2. Using recover to catch panic and continue 50% 失败

    Does not fix root cause; logic may be inconsistent.
