次のような単純なフラスコアプリを実行します。
from flask import Flask
app = Flask(__name__)
@app.route('/')
def welcome():
return "OK"
app.config.update(
DEBUG = True
)
if __name__ == '__main__':
app.run(use_reloader = False)
私がそれを実行して訪問すると、時々(常にではありませんが)リクエストに応答できず、例外がスローされます:
Exception happened during processing of request from ('127.0.0.1', 54481)
Traceback (most recent call last):

self._sock.sendall(view[write_offset:write_offset+buffer_size])

この障害の原因がわかりませんか?どうすれば解決できますか?
どうすればtry except
それをキャッチできますか?
