I used Selenium Grid Hub and Nodes to collect data, including selenium/hub: 3.141.59-iron
and selenium/node-firefox: 3.141.59-iron
, but one day after running, selenium-hub hung the following exception:
INFO exited: selenium-hub (exit status 137; not expected)
selenium/node-firefox exception is:
INFO [SelfRegisteringRemote$1.run] - Couldn't register this node: The hub is down or not responding: Failed to connect to selenium-hub/172.24.0.2:4444
What should I do?
