根因分析

aiohttp ClientSession 泄漏连接，或每个请求都创建且未关闭，耗尽了进程文件描述符上限。

English

aiohttp ClientSession leaked connections or was created per request without closing, exhausting the process file descriptor limit.

generic

解决方案

  1. 95% 成功率 
    connector = aiohttp.TCPConnector(limit=100, limit_per_host=20)
async with aiohttp.ClientSession(connector=connector) as session:
    await run_all(session)
  2. 93% 成功率 
    async with session.get(url) as resp:
    data = await resp.read()  # response released on exit

无效尝试

常见但无效的做法:

  1. 70% 失败

    Delays the failure but the leak continues; process eventually hits the new limit.

  2. 85% 失败

    Sessions hold OS resources until explicitly closed; GC does not close sockets.
