Hi, guys,

We find an issue related to job submit:

1) One team use “lavacli” to submit request, and sometimes it will report next:

07-Sep-2020 16:37:35        Unable to connect: HTTPConnectionPool(host='lava-master.sw.nxp.com', port=80): Read timed out. (read timeout=20.0)

Looks this error happens at next, what do you think about this issue?

try:

            # Create the Transport object

            parsed_uri = urlparse(uri)

            transport = RequestsTransport(

                parsed_uri.scheme,

                config.get("proxy"),

                config.get("timeout", 20.0),

                config.get("verify_ssl_cert", True),

            )

            # allow_none is True because the server does support it

            proxy = xmlrpc.client.ServerProxy(uri, allow_none=True, transport=transport)

version = proxy.system.version()

        except (OSError, xmlrpc.client.Error) as exc:

            print("Unable to connect: %s" % exc2str(exc))

            return 1

2) Another team write their own python code using XMLRPC to submit job, did something like next, it reports next:

ERROR in XMLRPC.py:submitJob:63 msg: Failed to submit job, reason: <ProtocolError for chuan.su:chuan.su@lava-master.sw.nxp.com/RPC2: 502 Bad Gateway>!

try:

                job_id = self.connection.scheduler.submit_job(job)

                self.logger.debug("Successed to submit job , job_id: %d, platform; %s!",job_id,platform)

                return job_id

            except Exception as e:

                self.logger.error("Failed to submit job, reason: %s!",str(e))

                return None

We are currently using lava server version 2020.08, guys told me in the past days, we also encountered similar, but with very low probability. But recently it becomes very high probability.

I’d like to know if possible this will related to your changes to gunicorn eventlet? Or other possible reasons?

Thanks,

Larry
