Running 2.4.4-p2 on MBT-4220

Accessing the WebGUI appears to be causing OS-level hang (no response on WebGUI/SSH/PING).
Occurs after login and dashboard visible, then clicking any link. Traffic Graph is visible stoping after a few seconds.

As long as I don't access WebGUI at any point post reboot WAN network access to LAN all machines works fine.

SSH login in appears to be unaffected until WebGUI is accessed.

Restarting WebGUI or PHP-FPM via SSH console (before hang) does not seem to help.

/var/log/system.log appears only the log successful SSH/WebGUI logins prior to hang and syslogd init post restart.

Last few records to Telegraf/InfluxDB suggest the a small spike in User/System process usage:

System: 5%
User: 6%
Idle: 88%

That isn't a general issue with pfSense or the MBT-4220. Please contact our support team at and someone can help you with that hardware to ensure it's OK.

I'm pretty sure I experienced the same issue on 2.4.4-p1 and or 2.4.4-p2.

It did happen only for the initial few reboots while configuring a fresh install.
Login, login message printed on the console, admin could not pass the login page, ssh not accessible, resetting password or restarting php or the webconfigurator did not help.

After config was finalized it did not happen any more, but I cannot confirm this because few days later it start running dev snapshots.

I always believed was due some misconfiguration introduced by me.

It looks like this might be a problem with the way the dashboard system information widget reads the sysctls when you have powerd enabled.

I see exactly this on an MBT-2220 in 2.4.5p1 after I have enabled powerd. It boots and runs fine until I login. The dashboard is show for a few seconds and then it hangs and has to be rebooted.

That same machine cannot display all the sysctls, running 'sysctl -a' also results in a system hang. It does so whether or not powerd is enabled.
