Ken Giusti created DISPATCH-2192:
------------------------------------
Summary: Streaming link leak during TCP + iperf3 testing
Key: DISPATCH-2192
URL: https://issues.apache.org/jira/browse/DISPATCH-2192
Project: Qpid Dispatch
Issue Type: Bug
Components: Protocol Adaptors, Router Node
Affects Versions: 1.16.1
Reporter: Ken Giusti
Assignee: Ken Giusti
Attachments: interior.conf, qdrouterd-A.conf, qdrouterd-B.conf
Running the iperf3 test against a three hop router configuration results in the
number of streaming links on the inter-router connections to grow continually.
These links remain active and are never reclaimed, even after the iperf3 test
clients and server exit.
To reproduce - establish 3 routers using the attached configuration. Run the
iperf3 server:
iperf3 --server -p 8080 &
Run the iperf3 client several times, using many connections:
$ iperf3 -c 127.0.0.1 -p 8000 -P 100
Check the number of inter-router links:
$ qdstat -r RouterTcpA -l | grep inter-router | wc
422 8440 74272
The total number of links keeps increasing. It appears that each link still
has some traffic on it - undelivered or unsettled messages - which will keep it
from being reclaimed.
