I want to implement a function: When a test case in job is crush or return err(no zero),  the job can be rescheduled(or resubmit). Does it need to write  own event notification? Need monitor "job Incomplete" action?
In addition, according to lava xmlrpc doc, I input command in lava server  console:  python zmq_client.py -j 121 --hostname tcp://127.0.0.1:5500 -t 1200 .The was error :

    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
