I made the changes you mentioned and it works now.
Thanks for the help.

NetMQ now supports curve. Anyway I suggest to set both Send and
Receive Highwatermarks, especially when using curve. Make sure to set
it on edge sockets and proxy. I don't suggest to use zero but to
calculate the number according to your system tolerance. Also, you
might want to increase zeromq IO threads (default is one) as
encryption is CPU heavy.

I am doing some performance tests on ZeroMQ to compare it with
others
like RabbitMQ and ActiveMQ.
In my broadcast tests and to avoid "The Dynamic Discovery Problem"
as
referred by ZeroMQ documentation I have used a proxy. In my
scenario, I
am using 50 concurrent publishers each one sending 500 messages
with 1ms
delay between sends. Each message is then read by 50 subscribers.
And as
I said I am losing messages, each of the subscribers should receive
a
total of 25000 messages and they are each receiving between 5000
and
10000 messages only.
I am using Windows and C# .Net client clrzmq4 (4.1.0.31).
Code to reproduce the issue is available at
https://pastebin.com/SEqEhSL1 [1]
I have already tried some solutions that I found on some posts:
I have set linger to TimeSpan.MaxValue
I have set ReceiveHighWatermark to 0 (as it is presented as
infinite, but I have tried also Int32.MaxValue)
I have set checked for slow start receivers, I made receivers
start
some seconds before publishers
I had to make sure that no garbage collection is made to the
socket
instances (linger should do it but to make sure)
I have a similar scenario (with similar logic) using NetMQ and
it
works fine. The other scenario does not use security though and
this one
does (and that's also the reason why I use clrzmq in this one
because I
need client authentication with certificates that is not yet
possible on
NetMQ).
I have also tested this scenario with clrzmq but with no
security
and it worked
Does someone know another thing to check? Or has it happened to
anyone
before?
Thanks,
Davide Costa
