CodePudding user response:

Link channel to have the close, is close in the finally,
How much is the number of simultaneous connections, how much message size, start to see how much memory allocation,
From the several aspects under the self-check code,

CodePudding user response:

The building Lord solved excuse me? My project also appears the question, I don't have much connection count, a few long connection, the client report data much more special, so in a couple of days

CodePudding user response:

I am out of the question, was solved
