[zeromq-dev] cannot send big chunk via PUSH/PULL by pyzmq

[Li Ma]

Hi all,

I wanna test a simple application using PUSH/PULL to send a big chunk of data.
The application is straightforward.

Server part is to open a PULL socket while client part is sending >1MB
message per time via PUSH.

The socket is listened on the localhost only.

Any messages less than 200KB are working well, but messages greater
than 500KB is not working. The socket is stuck after handshake without
any exceptions.

By the way, I set a large size (>1MB) for SND/RCV BUF and tcp window
scaling is set to 1.

I'd appreciate any hints to make it work.
