Ganesh Murthy updated DISPATCH-1391:
------------------------------------
Description:
When the following program is run against the router, it crashes -
{noformat}
from proton.utils import BlockingConnection
from time import sleep
ROUTER_ADDRESS = "amqp://127.0.0.1:5672"
RECEIVER_ADDRESS = "examples-receiver"
c = BlockingConnection(ROUTER_ADDRESS)
count = 0
while True:
count += 1
r = c.create_receiver(RECEIVER_ADDRESS + str(count))
r.session.close()
if count == 5:
break
Here is the backtrace

This is happening because the pn_link references are not cleaned up on router
