Is timeout correct?

[Jianjun Mao]

Hi,

By default, mgo.Dial will set socket timeout with 60 seconds. But why my query returned read tcp timeout after 10 seconds ?

I use a fixed size session pool to do query, I don't know if there's something related to the reusing socket mechanism.

Can anyone explain this?

Thanks.

Hi Jianjun,

Per the documentation at http://gopkg.in/mgo.v2#Dial:

"Dial will timeout after 10 seconds if a server isn't reached."

Thanks for your reply.

I'm sorry for lack of error message.

The error is 'read tcp <ip>:20973-><ip>:7017: i/o timeout'  which is return by the Find().All() query command.

Can you please send a small reproducer example?  It needs to be self-contained so I can test it locally.

It's really hard to reproduce with small example...

Strange timeout seems disappeared after I upgrade labix.org/v2/mgo (2013) to gopkg.in/mgo.v2 (2015-06)...

The server version is 3.0.5 and deployed with mongo sharding.
