26.7 Series / Re: 26.7.1_1 memory leak

August 04, 2026, 06:04:28 PM

Think thats fixed it. I disabled DHCP6 on WAN

Memory usage isn't creeping up anymore. sat at just under 8% for the last hour.

Thanks for the help!

Thanks Cedrik,

And apologies, I should have realised that. I tned to work these things out by trial and error usually.

I did find a whole lot of entries like the below, not very high %mem at anywhere between .1 and .3 but a LOT of them.:

99972 I 0:00.13 127 127 0 70932 11076 - 6404 0.0 0.1 |-- /usr/local/bin/php /usr/local/etc/rc.newwanipv6 igc0 REQUEST

Is this potentially something to do with DHCP6? I think I have this enabled for my WAN connection but I have no idea if my ISP support it? I might try disabling to see if that resolves the issue.

Thanks again,

Mike

26.7 Series / 26.7.1_1 memory leak

August 04, 2026, 12:18:20 PM

Hi All,

Updated opnsense yesterday on my Protectli Vault FW4C and have had all sorts of issues since.

Upgrade from 26.1... Left me with no internet access (although opnsense could ping etc so had internet) I asssume it was dns related and after failing to resolve that after an hour or two I just did a fresh clean install of 26.7 as my setup is pretty straight forward.

Only issue is I seems to have some sort of memory leak. I can watch memory uisage keep climbing until it reaches near 100% and its gets unstable until I do a reboot.

Looking at activity under system - dignostics i can see multiple root processes that appear to be python steadily use more memory:

/usr/local/bin/python3 /usr/local/opnsense/service/configd.py console (python3.13){python3.13}

I also seems to end up with hundreds of these entries, all appearing to use more memory as time progresses?

I'm far from an expert on this stuff so not sure what this is or how to resolve it.

Any suggestions much appreciated!

Thanks

25.1, 25.4 Legacy Series / Instability and DNS issues since most recent firmware updates

February 25, 2025, 05:46:21 PM

Hi All,

I have a fairly simple opensense router setup in my home office on a Protecli vault FW4C device thats works beutifully, or at least did until yesterday evening. I did the most recent firmware updates (sorry can't remember exactly what they were but only remember it being two or three items) but ever since have had issues with DNS and DHCP, the whole opensense interface is also very laggy and slow, dashboard items don't load half the time, its also crashed too.

I'm relatively new to Opensense and not exactly a network guru either, so not sure where to start to fix this. I have shared the bug details for the crash through the Opensense reporting.

The main issue we've had is losing internet on the wifi (Ubiquiti APs managed by unifi). Devices are connected, DNS settings via DHCP just doesn't seem to be shared, If I set manual DNS on my phone for instance then its working, but via DHCP its not. Restarting the Vault helps but still flakey and laggy. Neither the System info or CPU info panels have loaded in dashboard for instance.

Any suggestions as to what going on or even how I roll the software version back would be appreciated.

Mike
