I've set up a simple asyncmongo/zeromq router to act as a message queue as well as manage writes to my datastore.
what I'm finding is that the connections are getting released or reused, so it eventually hits maxconnections and stops.
Here's what I'm working with. You can pass a few messages then it stops and starts throwing TooManyConnections

from zmq.eventloop import ioloop, zmqstream
from tornado import escape
from tornado import gen
loop = ioloop.IOLoop.instance()
db = asyncmongo.Client(pool_id='mydb', host='127.0.0.1', port=27017, maxconnections=5, dbname='chatforus')
ctx = zmq.Context()
receiver = ctx.socket(zmq.PULL)
broadcast = ctx.socket(zmq.PUSH)
receiver_stream = zmqstream.ZMQStream(receiver, loop)
broadcast_stream = zmqstream.ZMQStream(broadcast, loop)
message = escape.json_decode(msg)
if message["type"] == "msg":
message["ts"] = datetime.datetime.now()
(response,), error = yield gen.Task(db.msgs.insert, message)
did you find a solution or workaround for this problem?
Sorry for the noise. I just want to add that #45 contains a pull request that solves this issue.
Maybe this issue can be closed in favor of #45.
Hi thanks for following up on this issue. I ended up changing the way I deployed asycnmongo but I can't recall what all I did at this time. I won't have access to that code for a couple days. If there's an pull request that already fixes this, then it might be better if that's chosen.
#45 is precisely to fix this particular issue. It is deployed in production for a product of mine a has so far worked...
