Martin, I tried it already and if I introduce a small delay after binding a socket, then everything works as supposed to. However, I bind and then connect sockets sequentially from a single thread, so if these calls are synchronous they should be executed in a right sequence. Is there any "asynchronicity" in socket binding? If so then is there a way to disable it?
I also noticed that socket binding on Centos5 platform sometimes fails too. I will try adding another delay after socket creation and before binding but this error is more rare and harder to reproduce. I also tried it on non-Amazon machine to rule out their custom kernel, but result is still the same. > -----Original Message----- > From: zeromq-dev-boun...@lists.zeromq.org > [mailto:zeromq-dev-boun...@lists.zeromq.org] On Behalf Of > Martin Hurton > Sent: July 19, 2010 2:29 AM > To: 0MQ development list > Subject: Re: [zeromq-dev] "inproc" socket connection fails > onCentos5/AmazonEC > > Hi Dmitri, > > I think this is a timing issue; you call connect() before the bind () > has finished. > Try to postpone the connect() call by 1 second. > > - Martin > > On Mon, Jul 19, 2010 at 5:12 AM, Dmitri Toubelis > <dmitri.toube...@alkeron.com> wrote: > > Some more information on this issue.
