根因分析

对已过期或已停止的time.Timer调用Reset()，在Go 1.18+中不允许，除非正确排空通道。

English

Calling Reset() on a time.Timer that has already expired or been stopped, which is not allowed in Go 1.18+ without proper draining.

generic

解决方案

  1. 95% 成功率 Drain timer channel before Reset 
    if !t.Stop() { <-t.C }; t.Reset(duration)
  2. 90% 成功率 Use time.NewTimer and avoid Reset 
    t := time.NewTimer(duration); // use once and recreate if needed

无效尝试

常见但无效的做法:

  1. Using recover() to ignore panic 90% 失败

    Does not fix timer state issue.

  2. Calling Stop() before Reset() without draining 85% 失败

    Stop() returns false if already fired, but Reset still panics if channel not drained.
