fix(configure): service restart #5

Closed Guillaumebeuzeboc closed 1 year ago

Guillaumebeuzeboc commented 1 year ago

Using the restart keyword, is not working so good. XMLRPC is failing to access the port. Stop and then start works, The error most probably comes from the roscore. Since we restart the core application and then the teleop application. The error was:

Exception ignored in thread started by: <bound method XmlRpcNode.run of <rosgraph.xmlrpc.XmlRpcNode object at 0x7f974b8a3e50>>
