Christoph created PROTON-1898:
---------------------------------
Summary: Memory leak related to sending
Key: PROTON-1898
URL: https://issues.apache.org/jira/browse/PROTON-1898
Project: Qpid Proton
Issue Type: Bug
Components: go-binding
Affects Versions: proton-c-0.24.0
Reporter: Christoph
Assignee: Alan Conway
I started implementing a GO application using qpid electron. There is one
connection used to receive messages (at-least-once). It works nicely with low
memory consumption, multiple links and multiple go routines, 50 bytes payload,
up to 3000 msg/s
But as soon as the application starts sending messages (to reply over the same
connection) memory consumption is continuously growing up to 2GB where I
stopped.
Even if electron does not leave many options for wrong usage there might be an
issue in the application.
So I tried the qpid electron example
"https://github.com/apache/qpid-proton/blob/master/go/examples/electron/send.go";,
the same issue.
To reproduce it:
* use the sample program, I just added connection options for SASL PLAIN
* let it send 100000 messages or more to one destination
My setup:
* windows 10 pro
* go1.10.2 windows/amd64
* qpid 0.24.0-rc1
* go files and lib build from same git repository clone and branch
* visual studio 2015, release build, no errors
* Broker: Solace VMR 8.11.0.1029 with different durable queues as source and
target
I tried also qpid proton 0.23.0 earlier, but saw the same problem.
I tried SendAsync and SendSync, both in 10-50 go routines in parallel.Finally,
with SendForget my worker routines were soon blocked and did not come back.
Best regards
Christoph
