Root Cause

An external command executed with exec.CommandContext exceeds the context deadline, causing the process to be killed.

generic

中文

使用 exec.CommandContext 执行的外部命令超过上下文截止时间，导致进程被终止。

Workarounds

  1. 90% success 
    ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second); defer cancel(); cmd := exec.CommandContext(ctx, "sleep", "30"); if err := cmd.Run(); err != nil { ... }

Dead Ends

Common approaches that don't work:

  1. 80% fail

    May hang indefinitely, consuming resources.

  2. 60% fail

    Doesn't solve the root cause; may still timeout for long-running commands.
