根因分析

Cloudflare Workers每个请求有128 MB内存限制；worker尝试分配超过可用内存，导致终止。

English

Cloudflare Workers have a 128 MB memory limit per request; the worker attempted to allocate more than available, causing termination.

解决方案

  1. 通过流式处理大响应而不是缓冲来优化内存使用。示例：使用response.body.pipeTo(writable)而不是将整个主体读入内存。
  2. 将worker拆分为多个较小的worker，处理请求的不同部分，减少每个请求的内存占用。

无效尝试

常见但无效的做法:

  1. Increase the memory limit in wrangler.toml 100% 失败

    Cloudflare Workers memory limit is fixed at 128 MB per request for all plans; cannot be increased.

  2. Enable auto-scaling to use more memory 100% 失败

    Workers don't support auto-scaling per request; each request is isolated and limited to 128 MB.
