pfsense 2.7.0 crashes daily - help please

daniel_id

Hello, I keep having daily crashes, since a couple of days. I am on pfsense 2.7.0 on a Protectli FW4C. My network is quite simple 3 VLAN, one of them with VPN, no packages installed.

Here from the textdump crash reports:

Would be great if someone can look at it and point me in the right direction how to solve it. Is it an hardware issue, or something else?

Appreciate your feedback and thanks in advance for your support.

All three crashes are shown in Netstat and you have a bunch of errors:

config_aqm Unable to configure flowset, flowset busy!
config_aqm Unable to configure flowset, flowset busy!
config_aqm Unable to configure flowset, flowset busy!

That's normally just ugly: https://redmine.pfsense.org/issues/8991

What packages do you have installed?

Is there some reason you have not upgraded to 2.7.2?

Steve,

thanks for your feedback and the further information. My limiter settings to reduce bufferbloat might have caused the crashes.

I have changed the setting on AQM to Tail Drop on both, limiter (pipe) and child queue and scheduler to fq_codel on limiter (pipe) now.

I hope the errors:
"config_aqm Unable to configure flowset, flowset busy!" don't show up anymore and the system doesn't crash. Let's see!

Currently, I have no packages installed. There is no real reason, why I have not upgraded to 2.7.2. Well, the update does't show up in the GUI. But I'll try to do the update by command line.

Thanks. Daniel
