Network manager dumping coredumps every two hours

English Applications
1

I happened to notice that networkmanager is dumping coredumps approximately every two hours.
I see no operational changes on computer . I am curious as to what is going on and how to diagnose this issue. There seems to be no diagnosible info on the networkmanager dumps.

Thanks for any guidance.

sudo journalctl -xe --unit=NetworkManager might provide some useful information - give that a shot and see if that tells you anything.

I am not conversant in network things. Looks like wifi is the source. Here is the command output.

Unfortunately, that’s not showing a crash - the messages there are normal and nothing concerning.

dmesg might show more useful information. If it’s too large to post here, you can put it on paste.opensuse.org and provide a link to the paste here.
