Subject: Re: [Boost-users] asio: async_write handler not called in Linux but called in Windows

Further debugging the issue, I found that if I pass a small buffer (like
10KB) to write, the async_write handler (HandleWrite) is called. I was passing
128 MB of data to be written in a single async_write call. Does this has
something to do with not calling the write handler? In Wondows also I am
passing 128 MB buffer, but it works!
