QueuedAioHttpTransport throwing ServerDisconnectedError/ClientOSError exceptions.

[bt-wil]

Environment (python v3.6):

aiohttp==2.2.5
raven==6.1.0
raven-aiohttp==0.6.0
sentry==8.22.0

I tried using the QueuedAioHttpTransport for the transport and noticed that it generates errors if there are too many alerts firing.

#!/usr/bin/env python3
import asyncio
from functools import partial
import logging

import raven
from raven.handlers.logging import SentryHandler
from raven_aiohttp import QueuedAioHttpTransport


logging.basicConfig(
    format='[%(asctime)s] %(levelname)s - %(message)s',
    datefmt='%Y-%m-%d %H:%M:%S',
    level=logging.INFO
)
LOG = logging.getLogger(__name__)


if __name__ == '__main__':
    loop = asyncio.get_event_loop()

    dsn = 'http://<key>:<secret>@localhost:9000/1'
    transport = partial(QueuedAioHttpTransport, workers=1, loop=loop, keepalive=True)

    client = raven.Client(dsn, transport=transport)
    handler = SentryHandler(client)
    handler.setLevel(logging.ERROR)
    logging.getLogger().addHandler(handler)

    for _ in range(2):
        LOG.error('test')

    loop.run_until_complete(client.remote.get_transport().close())
    loop.close()

Running the script produces:

[2017-12-06 12:10:30] ERROR - test

b"['test']"

Sometimes, aiohttp.client_exceptions.ClientOSError would be thrown instead of aiohttp.client_exceptions.ServerDisconnectedError. Using AioHttpTransport as the transport did not cause any issue.

Does messages in this case successfully send to the sentry on not?

[bt-wil]

No, the messages gets lost.
