[zeromq-dev] MAX ZMQ Sockets in a Context

Dear All, There seems to be a *limit* on the number of zmq_sockets that can be created in a zmq_context. I am using *inproc* transport. In my tests the maximum possible is between *500-515 sockets per context *on my linux development box (Ubuntu 10.10 Desktop, Core i3 530, 4 Gb DDR3 Ram). Is thi

Hello Jonathan & Martin, What does it exactly mean? Does the program crash in such case or what? - Martin No it does not crash! Just that the poll/epoll will not return any events on ZMQ_FD. Here is the schematic that dint work... 1. Create a XREQ socket 2. Set the identity 3. connect to XREP e

Libev is a strictly Level-Triggered event loop wrapper. The author points out that its is required for portability. So the problem you mentioned does not arise as we are using Level-Triggered event reactor. Praveen On Thu, Dec 16, 2010 at 12:08 AM, Martin Sustrik wrote: > Hi Praveen, > > I thi

[zeromq-dev] External Event Loop

Hello All, I started working on the external event loop integration for ZMQ sockets using getsocketopt and ZMQ_FD. I am using a wrapper around Libev for the OS specific event loop abstraction. But the event loop is not working on FDs from ZMQ sockets. Its not returning any events. Given below is

Hello All! I was just reading the Advanced Stuff chapter of the guide and found the XREP socket as a router pretty interesting. I just need a clarification that is not found anywhere in the guide or else where. XREP(Router) uses the identity envelope to route the message to the correct connected
