How to resolve the problem about "xxx" exec not allowed currently since an operation (xxx) is in progress

[1201110211]

Ixnetwork API Server: 9.30.2212.7 ixnetwork-restpy: 1.3.0 ix-os: 9.30.3001.12

i use ixnetwork-restpy to control the ixianetwork api server in windows since upgrade from ix-os9.10 to ix-os 9.30, sometimes, the server start to response the code 202, state EXCEPTION, and can not recover I have tried to use TestPlatform().Sessions.find().remove(), but it didn't work, can not resolve this Execution by ixnetwork-restpy

Any method to resolve this problem? i do not want to reload the Ixnetwork API Server

this is the code and traceback: from ixnetwork_restpy import SessionAssistant self.session_assistant = SessionAssistant(IpAddress=self.Host_Ip, UserName=self.UserName, Password=self.Password, LogLevel=SessionAssistant.LOGLEVEL_INFO, ClearConfig=True) File "F:\pycharm_project\func_auto_test_box\keywords\Testerlibrary\TesterTrafficStatistics.py", line 444, in cleanup_session self.session_assistant = SessionAssistant(IpAddress=self.Host_Ip, UserName=self.UserName, File "C:\python38\lib\site-packages\ixnetwork_restpy\assistants\sessions\sessionassistant.py", line 113, in init self._ixnetwork.NewConfig() File "C:\python38\lib\site-packages\ixnetwork_restpy\testplatform\sessions\ixnetwork\ixnetwork.py", line 2116, in NewConfig return self._execute("newConfig", payload=payload, response_object=None) File "C:\python38\lib\site-packages\ixnetwork_restpy\base.py", line 452, in _execute response = self._connection._execute(url, payload) File "C:\python38\lib\site-packages\ixnetwork_restpy\connection.py", line 289, in _execute return self._send_recv("POST", url, payload) File "C:\python38\lib\site-packages\ixnetwork_restpy\connection.py", line 572, in _send_recv return self._poll() File "C:\python38\lib\site-packages\ixnetwork_restpy\connection.py", line 640, in _poll return self._process_response_status_code( File "C:\python38\lib\site-packages\ixnetwork_restpy\connection.py", line 476, in _process_response_status_code raise BadRequestError(message, response.status_code)

Before the problem happened, i use these api: (1) ixnetwork = self.session_assistant.Ixnetwork capture_config = ixnetwork.Vport.find(AssignedTo=capture_port).Capture capture_config.HardwareEnabled = True capture_config.SoftwareEnabled = True capture_config.Start() (2) tmp_traffic = ixnetwork.Traffic.TrafficItem.find(Name=tmp_name) tmp_traffic.StopStatelessTraffic() step1 and step2 between about 5 second
