[Time] Name	Message
[00:56] tarcieri	cremes: hmm, k
[00:58] tarcieri	cremes: the only difference I see is you're synchronizing receiving. I'm having trouble doing concurrent sends
[00:58] tarcieri	(concurrent sends synchronized with a mutex)
[01:05] tarcieri	or in other words, it's the push socket that's having trouble
[01:58] sigmonsay	Wow, this is very weird
[01:58] sigmonsay	Assertion failed: new_sndbuf > old_sndbuf (mailbox.cpp:183)
[01:59] sigmonsay	I'm using req/reply pattern and a request was likely interupted. Does this mean my servers state it entirely out of wack?
[02:06] mikko	sigmonsay: are you using the socket from multiple threads?
[02:06] sigmonsay	Not where this connection is occuring. The client is threaded, but I use a new socket. Only do I share the context
[02:06] mikko	also, which version of zeromq is this?
[02:07] sigmonsay	This is only under load also. libzmq1 2.1.7 from Martin Lucina
[02:08] mikko	sigmonsay: this is fixed in 2.1.8 i believe
[02:08] sigmonsay	Hmm
[02:08] mikko	https://github.com/zeromq/zeromq2-1/blob/master/NEWS#L81
[02:08] sigmonsay	I see on the mailing list bits about raising tcp rmem and wmem. Prolly not a real fix?
[02:09] mikko	sigmonsay: why not upgrade the version?
[02:09] sigmonsay	I will do so, but just was using someone elses repo. I'll have to dig up where I got it and check if newer bits exist.
[02:09] sigmonsay	This is my initial interaction with 0mq
[02:09] mikko	which repo?
[02:09] mikko	debian?
[02:10] sigmonsay	ubuntu lucid, its a ppa I think
[02:10] sigmonsay	ppa.launchpad.net/chris-lea/zeromq/
[02:11] mikko	anyway, newer version should fix that issue
[02:11] mikko	i gotta head to bed
[02:11] mikko	good night
[02:11] sigmonsay	thanks, good night
[11:01] CIA-79	jzmq: 03Gonzalo Diethelm 07master * r6ceaa43 10/ (src/Makefile.am src/Makefile.in src/org/zeromq/ZFrame.java): Merge pull request #85 from aorzecho/master ...
[11:30] jivs	http://www.amplicon.com/campaigns/wireless-agenda.cfm
[14:06] cremes	tarcieri: here's a small program that i think mimics your requirement
[14:06] cremes	tarcieri: https://gist.github.com/1336564
[14:06] cremes	tarcieri: it creates 1 push and 1 pull socket; it starts up a bunch of threads and pushes to that single socket
[14:06] cremes	tarcieri: the push socket is protected with a mutex
[14:07] cremes	i ran it with 10_000 messages and 500 threads; it exited cleanly and no errors were detected at runtime
[14:07] cremes	feel free to adjust the parameters (and transport to inproc) to test for yourself
[14:07] cremes	i'm going to be offline for the next 4 days; i may be able to respond to email via my iphone but don't count on it :)
[14:08] cremes	good luck... i hope celluloid is a good netizen by the time i get back!
[14:10] cremes	tarcieri: btw, the test with those params took about 2m20s to run on my box
[17:45] nerus	Hi
[17:46] nerus	I am trying to run a c++ version of a zeromq request-reply example
[17:47] nerus	getting a really silly error, is there a faq/wiki page on how to troubleshoot?
[18:07] sustrik	what erro?
[18:07] sustrik	error?
[18:27] nerus	sustrik_, sorry was trying out something
[18:28] nerus	sustrik_, worker.cpp:1:20: fatal error: zmsg.hpp: No such file or directory
[18:28] nerus	but the hpp file is already available in /usr/local/include
[18:29] sustrik	zmsg.hpp?
[18:29] sustrik	what's that?
[18:29] nerus	sustrik_, oops
[18:31] nerus	sustrik_, this is where it came from - http://zguide.zeromq.org/cpp:ppworker
[18:31] nerus	but I just assumed it was complaining about zmq.hpp
[18:31] nerus	changed it to zmq and it works fine
[18:31] nerus	sustrik_, thanks :)
[18:33] sustrik	you are welcome
[18:44] nerus	sustrik, finally figured it out - https://github.com/imatix/zguide/blob/master/examples/C++/zmsg.hpp
[22:05] dirtmcgirt	the the ZMQ_REP endpoint terminates, the zmq_recv on the ZMQ_REQ hangs - how do i get the error condition back?
