Asynchronous connection failed when several users test site about momoko HOT 9 CLOSED

There's not enough information for me to say what could be wrong. I only see that no connection can be made. Are you sure your PostgreSQL server is running and that the database host, post, username and password are correct?

Okay,
Here is some information about database server:

• PostgreSQL 8.4.13 (i386 build)
• OS Debian/GNU Linux

Web server (x86_64)

• python 2.7
• momoko 0.5
• tornado 2.4.1

from momoko.

Hmm... I see on interesting thing...
When I use on single-process server, I won't get this error

server = HTTPServer(app, on_keep_alive=True, xheaders=True)
server.bind(8888)
server.start()
IOLoop.instance().start()

...
or
...

server = HTTPServer(app, on_keep_alive=True, xheaders=True)
server.listing(8888)
IOLoop.instance().start()

When I use multi-process server, I will get this message.

I hope that will help you

Thanks. Going to see if I can find a solution.

NP. You're welcome.
I'm realy interested in your solution =)

from momoko.

Everything seems to be working here. Even when I let the HTTP server spawn multiple processes.

from momoko.

I analyzed configs postgresql and find that max_connection was overloaded when I runned tornado in multi-processing mode. After, I increased max connection number problem has gone.

Sorry...

from momoko.

Hmm, ok. There should be a proper warning when this happens. I'll take that in account for 1.0.0. Thanks!

You're welcome. I look forward for a new version =)
Thanks for work =)
