Python tests fail/hang with ulimit -n 65536
-------------------------------------------
Key: QPID-3922
URL: https://issues.apache.org/jira/browse/QPID-3922
Project: Qpid
Issue Type: Bug
Components: Python Client
Affects Versions: 0.17
Reporter: Alan Conway
Assignee: Rafael H. Schloming
Priority: Minor
Some of the python tests fail and hang if run with ulimit -n 65536. To
reproduce in a c++ build go to the src/tests directory and:
su root -c 'ulimit -n 65536; make check TESTS="start_broker python_tests
stop_broker" PYTHON_TESTS=*endpoints.SetupTests*'
Several tests fail and then testOpenReconnectURLs hangs as follows:
qpid.tests.messaging.endpoints.SetupTests.testOpenCloseResourceLeaks
