100% /usr/local/sbin/check_reload_status after gateway down
-
@stephenw10 Unfortunately did not check that. I did now use a physical port for that connection and will see if the error still appears. Otherwise it's an issue with VLAN WAN interfaces as it seems.
-
I've yet to see this here on any system. If anyone has a way to replicate this please let us know so we can dig into it.
-
I have check_reload_status at 100% too. It must be related to OpenVPN for me when the interface is removed from my gateway routing group.
-
Only removing it from the group prevents it? The interface is still assigned?
-
I'm seeing "check_reload_status" persistently using 50-99% of CPU for over a month now.

-
If you kill that process does it respawn?
Is there any reason you're not running 23.05.1?
-
I had to use "kill -9" to terminate it.
Waited for 5 mins and didn't see it respawning.
Being onsite I decided to do a full reboot anyway.Regarding pfSense versions.
I have 3 x Netgate 3100 appliances. 2 live and one spare. One of the live ones is located in a distant datacenter so upgrading it remotely is too risky.
Typically I upgrade all 3 firewalls only about once per year when I have other reasons to travel to the dc. I import config to the spare one and just physically swap them around followed by some testing. If anything goes wrong then I just swap them back. -
BTW: after a reboot I was able to ssh to the fw but couldn't elevate to root as my user any more: "xxx is not in the sudoers file".
I think I checked everything (sudo installed, member of admins, sudo config) and couldn't see why. Sudo worked fine just before the reboot with no changes made.
Luckily my web GUI access still worked so I added my user explicitly under /pkg_edit.php?xml=sudo.xml which allowed me to root in shell.
-
Hmm, that was after upgrading? Or has it worked since then and just stopped now?
I'm not aware of any issues with sudoers in 23.05(.1). -
What I did last time (about 3 months ago):
-
installed a vanilla 22.01 image from USB (offline),
-
went online,
-
upgraded to 23.05 (2 stages if I remember correctly),
-
restored config.xml (previously exported from 22.01).
Once the FW booted up everything was working (including sudo) and I haven't restarted it until today.
-
-
Hmm, odd. Your user was in the admins group and that group was enabled in sudo for the command you were trying to run?
-
I don't know for sure how sudoers looked like before (unable to read) but this is how it looks like after 2 users have been explicitly added from web GUI:
cat /usr/local/etc/sudoers
root ALL=(root) ALL
admin ALL=(root) ALL
%admins ALL=(root) ALL
myuser ALL=(root) ALL
someotheradminuser ALL=(root) ALLid myuser
uid=2000(myuser) gid=65534(nobody) groups=65534(nobody),1999(admins)
-
I experienced this when I briefly turned off the DSL modem connected to pfSense WAN. When the gateway came back up, /usr/local/sbin/check_reload_status was consuming 100%. I killed that pid but believe it respawns and remained at 100%. I resorted to rebooting.
I am on 2.7CE and don't recall seeing this happening before on the rare occassions I've powered off the modem. -
I have the same issue on CE 2.7.0-RELEASE. I installed WireGuard and FRR Packages a couple of days ago (running 2 wireguard VPNs with OSPF), after which it started. Possibly process check_reload_status is using 100% after interface flap, but am not 100% sure. Shutting and no shutting an interface did not reproduce the problem. Manually restarting services in the UI did not work, as well as restarting the WebConfigurator. After using kill -9 I managed to end the process without rebooting. I am aware WireGuard is still under development, but maybe a fix can be found.
-
So you were not using OpenVPN when this started? And after killing it it didn't return?
-
@stephenw10 No, I restarted ovpn service, and nothing changed. Next time this happens I will a stop the ovpn service for a couple of minutes to see if the behavior changes.
-
This just happened to me on CE 2.7.0 on the backup CARP node. Have OpenVPN and Wireguard both. OpenVPN was stopped (due to being the backup node). Stopped Wireguard, no change.
kill -9the process and it came back but at 0% usage. Rebooted anyway to make sure the node is not in a weird state in case I need it.Edit: looks like CARP was flapping between master and backup for a minute right before this happened. Will dig into that.
-
Mmm, check the logs when that happened for anything unusual. Flapping interfaces could cause it to queue a number of events. Perhaps hit some race condition....

Nothing has been specifically added to address that AFAIK. But you should upgrade to 23.09.1 to make sure the behavior exists there. Or doesn't.
