Root Cause

All goroutines are blocked waiting on channels or locks with no way to proceed, causing a program deadlock.

generic

中文

所有goroutine都阻塞在通道或锁上，无法继续执行，导致程序死锁。

Workarounds

  1. 90% success 
    Use buffered channels or select with default to avoid blocking indefinitely. Ensure there is a way for goroutines to exit.
  2. 85% success 
    Implement a timeout using context.WithTimeout to break deadlocks.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    If the existing goroutines are waiting on each other, adding more will not resolve the circular wait.

  2. 80% fail

    Sleep does not resolve the underlying synchronization issue; it only delays the deadlock detection.

  3. 70% fail

    This breaks the program's logic and may introduce data races.
