why insert data prompt : "couldn't connect to server "

[gmail]

Hi:

when I insert 2G data , each document is 2k, when I insert about 30000 ,the client prompt: "couldn't connect to server xxxxx", after a few second it can insert normally, and after insert another thousands date , the client prompt the error again.

when insert a new document I start a new connect. I used 16 thread to insert data!

how to fix the problem?

the error is just as following:

If you are opening a new connection with each insertion you are likely overloading the maximum number of connections your server can accept.
