Memory overusage on (*Transport).dialConn

[abdivasiyev]

In our production, we get massive memory usage on (*Transport).dialConn method in a 5 minute period. But I am not sure how to resolve this issue. This occured when all our requests got timeout because of non-working services. In a normal day, this have never been occured.

In this case setting SetMaxConnsPerHost and SetIdleConnTimeout options of Transport helped us. If these options are not set, the pool of the client connections are unlimited and tries to open infinite connections.
