Title: Page Fault / Fatal Trap
Post by: dredhorse on February 01, 2017, 06:02:11 pm

Hi,

I get https://www.dropbox.com/s/pe2vqbjmx0k65tj/OPNSense_2017-02-01_17-59-14.png?dl=0

This is running on ESXi 6.5, the system was upgraded vom 16.7 fully patched. I rolled back to that point (snapshots for the win).

Any idea? I can also roll forward again if needed if that helps troubleshooting.

Regards

Don

It has 2 Gig, I can give it more.

Dashboard shows that it is using around 1 GB.

Can you disable shaper before upgrade? Can you live on 17.1 without the shaper if this keeps crashing? It's definitely shaper related is what I'm trying to say.

I think there are patches in FreeBSD (not 11.0) that we could try in the next week.

sure can do, it didn't work in 16.7 nevertheless (MultiWan), it started working in 17.1 but... better a working setup than crashes.

Hi Don,

Did this happen during a (re)configure or under traffic?

I found no bugs or patches regarding wf2pq_dequeue() in FreeBSD, but remember seeing it once in one of our crash report without an e-mail address attached, so no way to contact the user.

This is specifically for "Weighted Fair Queueing" option and other algorithms have their own implementations. Not sure where to go from here. At least a "bt" command dump from that panic would be a plus to have on record.

Franco

Hi, 

attached the config https://www.dropbox.com/s/xwmi9lcysrjv20h/Traffic_Shaper_2017-02-02_19-07-57.png?dl=0

It did happen during traffic. But also as I did reconfigure some stuff in the webproxy, but I guess that is unrelated as I did just checkbox something.

Don't know how to do the bt command... vm interface is not accessible and I did notice it because my network connection went down, so I guess that ssh will also not be possible.

I could probably get you a VM crashdump (NMI) that can be triggered.

Hi Don,

Following up on this only now, sorry. Dump won't be helpful as this is out of scope and would need to be reported to FreeBSD. But the Weighted Fair Queueing option is not maintained much as far as I can see so circumventing the problem by using a different algorithm would be an option when the problem recurs.


Cheers,
Franco

Hi,

no Problems, I will look into at, atm I don't have really any need for traffic shaping per see.

Thanks for your help.
