We appreciate you go through Apollo documentations and search previous issues before creating an new one. If neither of the sources helped you with your issues, please report the issue using the following form. Please note missing info can delay the response time.

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 14.04):14.04
• Apollo installed from (source or binary): source
• Apollo version (1.0, 1.5, 2.0, 2.5, 3.0):last version after installing the Apollo, I download a bag by

python rosbag_helper.py demo_3.5.record

and then:

cyber_recorder play -f docs/demo_guide/demo_3.5.record --loop

however, the terminal shows that file: docs/demo_guide/demo_3.5.record, chunk_number: 3, begin_time: 1546888377338834894 (2019-01-07 14:12:57), end_time: 1546888422886740928 (2019-01-07 14:13:42), message_number: 61615 earliest_begin_time: 1546888377338834894, latest_end_time: 1546888422886740928, total_msg_num: 61615 [RTPS_MSG_OUT Error] maxMessageSize cannot be greater than sendBufferSize -> Function init [RTPS_PARTICIPANT Error] Cannot create participant, because there is any transport -> Function createParticipant [PARTICIPANT Error] Problem creating RTPSParticipant -> Function createParticipant E0922 17:38:50.699831 9185 topology_manager.cc:81] [cyber_recorder] init manager failed. Segmentation fault

Could you please help me to solve this problem?

Although I met this error, my dreamview runs successfully, and the ego-car can also run. What's the reason?

Best, Xin

OK, thanks for your feedback，we have not reproduced this problem locally，could you provide core stack information. you can find the core file in /apollo/data/core directory, and use gdb tools to get stack information.

HI, @natashadsouza @quning18 I'd like to ask how to stop the recording process, started with command cyber_recorder record -a -o 1.record.

I tried "Ctrl+C" directly, but after it's stopped, there are multiple segments created,

-rw-r--r--  1 tangyun apollo 2152104299 Dec 13 10:52 1.record.00000 
-rw-r--r--  1 tangyun apollo  957506491 Dec 13 10:52 1.record.00001

the first one about 2GB in size, and second one about 900MB.

then I tried both cyber_recorder play -f 1.record.0000 and cyber_recorder play -f 1.record. Both not working with following error:

tangyun@in_dev_docker:/apollo/test$ cyber_recorder play -f 1.record.0000

Any help is highly appreciated. Thank you.

the recorded file size turned out to be too large... If I only record selected channels, instead of all channels, the recorded file size would be much smaller and it can be re-played later.

Hi ntutangyn, May I ask you why you need to record a bag ? Do you need it for debugging? I am working with Apollo+lgsvl stack, and my goal is to debug the Perception module. Do I need to the recorded bag to debug the module? Thanks in advance for your response.

[ntutangyun]

@Avps1 Hi, I recorded the messages to check out the actual data of all the channels in runtime. I'm not testing the perception module, but to debug it, I think you need to record all the input channels to the perception module (such as lidar, camera data) and the output channels of the perception module. (perception/obstacles and traffic lights.)

It'd be better if you could record the internal channels of perception module. But I'm not sure if that's possible.

[ntutangyun]
