--------------------------------
Summary: linked_list-test occasionally fails with webserver port
bind failure: address already in use
Key: KUDU-2738
URL: https://issues.apache.org/jira/browse/KUDU-2738
Project: Kudu
Issue Type: Bug
Components: test
Affects Versions: 1.9.0
Reporter: Mike Percy
Occasionally I see linked_list-test fail with the following error on Linux in
an automated test environment:
{code:java}
E0306 23:35:25.207222 19523 webserver.cc:369] Webserver: set_ports_option:

(Address already in use){code}
I am not sure what would have bound to 0.0.0.0:49008 for a short period of
time, or used 126.14.25.194:49008 as an ephemeral address / port pair since
it's such a unique loopback IP address.
