根因分析

在没有相应RLock的情况下调用RUnlock，通常是由于递归读锁定。

English

Calling RUnlock without a matching RLock, often due to recursive read locking.

generic

解决方案

  1. 99% 成功率 
    mu.RLock(); defer mu.RUnlock()
  2. 95% 成功率 
    Restructure code to hold lock only once per goroutine.

无效尝试

常见但无效的做法:

  1. 85% 失败

    RLock is not reentrant; multiple RLock without unlock causes deadlock or panic.

  2. 90% 失败

    Attempting to upgrade read lock to write lock causes deadlock.
