dhcp6c crashing on Signal 10
« on: November 08, 2021, 03:52:32 pm »
It says it made a core dump, but I don't see one.  Anyone else seeing this?

It seems(?) to be related to renew, and on ATT Fiber if that helps any.

Does anyone have any clues at all on this?  How can I get stuff to help get it diagnosed and hopefully fixed?

No other reports of this AFAIK. Firstly, can you set log level to debug for dhcp6c. If there's a core dump, I think it ends up in root, but I may be wrong.

Just once, or is it a repeat offender...?

repeat offender on a regular basis.  Where do I set the debug level for dhcp6c?

Hopefully this isn't due to comments or invisible white space in that override script...!

Not sure about setting debug level. @marjohn56 would know better.

Perhaps you could run it from the console shell in debug and foreground modes...

Wish I could help more but offline for next several hours... 8^d

i found the core.  I just had a system panic, which I dutifully sent to the developers.  We'll see if the dhcp6c stuff calms down. 

Where can I get the symbols for dhcp6c?

I also have the level set to debug on the interfaces -> Settings page.  Any help is appreciated.  Also more than happy to arrange access. (It's my home FW).

Yes, it's at debug.  What can I offer to help here?

How often does your lease renew?
