[electron/go] Memory leak seen when AtLeastOnce is used

    Details

    • Type: Bug
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: proton-c-0.24.0
    • Fix Version/s: None
    • Component/s: go-binding
    • Labels:
      None
    • Environment:
      RHEL 7.5, Go 1.10.2

      Description

      The test program located here: 
         https://github.com/redhat-nfvpe/telemetry-bench
       
      runs out of memory when AtLeastOnce is enabled instead of AtMostOnce.
      The program tests throughput and connects to a 1.2 QDR.  The program
      is generating about 20k messages per second and all messages are being
      ack'd.  However, the program memory quickly hits several gigabytes and eventually
      crashes due to a lack of memory.  When the the LinkOption is set 
      to AtMostOnce, the program runs for hours with steady memory usage.  The problem also occurs on fedora with proton-c-0.22.
