Error to display multicast packet
Hello,
Thanks to supply wireshark.
My device transmit data as source port 5101 ~ 5108 in UDP. And destination port 5100, and support Multicast packet 60001 ~ 60008.
This is normal packet.
My device send data such as normal packet image. 5104 : transmit to 5100 and 60004 5102 : transmit to 5100 and 60003 (transmit from one source port to two destination port(5100 and multicast port(60001 ~ 60008)
But, wireshark doesn't display some multicast packets.
But, sometimes doesn't display(capture) multicast packet such as error packet image.
So, wireshark display is good after click "Restart current capture".
This symptom occurs often.
I upload the log file in share folder. https://drive.google.com/drive/folder...
ZMG-390_Log.pcapng Normal operation is until line 948. My device pause to transmit data. and restart. Wireshark is no capture multicast packet after line 949.
This file is after "Restart current capture". ZMG-390_Log_restart.pcapng
Thanks.
Best regards, Baek.
v3.4.4 and v3.4.5 are same conditions.
Can you give more detail about what the error is? (What is the difference between the screenshots?)
Thanks for comment.

When this situation, I click "Restart current capture" and it is recovery.
Thanks for the explanation. Can you provide a capture file that has this issue?
okay. I will capture the receive packets at tomorrow. and I will upload it.
Is this post analysis or live analysis? What I found is permit Wireshark to finish whatever it doing before trying a new one. Wireshark doesn''t crash or complain, but the results will be skewed.
It is live analysis. I capture the log file. This result is not captured as multicast packet.
