Alan Conway commented on PROTON-1871:
-------------------------------------
FYI - some time ago I wrote a fluentd plugin based on proton:
[https://github.com/ViaQ/docker-fluentd/tree/master/amqp_qpid]
Just in case it is of interest, it has nothing to do with the bug you've
reported.
I'll investigate the memory leak, thanks for reporting it.
> Ruby leaks memory sending messages
> ----------------------------------
>
> Key: PROTON-1871
> URL: https://issues.apache.org/jira/browse/PROTON-1871
> Project: Qpid Proton
> Issue Type: Bug
> Components: ruby-binding
> Affects Versions: proton-c-0.23.0
> Reporter: roi costas
> Assignee: Alan Conway
> Priority: Major
> Attachments: out_amq.rb, valgrind.txt
>
>
> We have developed a simple fluentd output plugin which only sends messages to
> AMQ. Sending messages with sender.send, memory increases continuously and it
> is never released, not even when message processing is stopped.
> The qpid-proton code is really simple and we have checked that it is
> sender.send the one that leaks memory.
> I have run memory_profiler, and the leak does not seem to by in ruby but in
> C++ code because both the number of objects and bytes remain between constant
> values. I have tried to debug it with valgrind but I cannot find the source
> class of the leak.
> I have attached the ruby code, ruby version 2.3.4.
