After updating Opnsense from 25.7.10 to 25.7.11_1 opening WebGUI eats all memory

[allenlook]

Disabled IDS yesterday and memory utilization dropped to 50% of the 8GB.

Left it on overnight, and this morning memory and swap were both over 85% consumed.

Restarted host discovery service for grins and memory dropped to 40% and is climbing back up, currently 50% memory and 30% swap.  System rarely used swap before now.

Memory got over 85%, swap over 85%, so I restarted IDS (I had reverted it yesterday using the command in the thread above) to see what that might do, but it never restarted and shortly after the network went down.

The console showed thousands of netstat_bind_fail errors, and I had to reboot it.  The messages were flying by, and I had to log in blind and press "Enter" a bunch of times to get the menu to flash on the screen as I didn't remember the menu number for reboot (it's 6), and then I had to guess whether it was "y" or "Y" or "Yes" to get it to reboot.

Back to 50% memory and 0% swap used, but climbing again.

I'll have to roll back if this keeps up.  For now I am keeping the web GUI off to see if that helps and I'm monitoring memory utilization with "top -asH".  I'm also not running IDS for now.

It started with 2048M free about 5 minutes ago, and it's down to 1922M in that time.

This morning, without IDS or Web GUI running overnight, the system was at 93+% memory used and 90+% swap used.

I have rolled back to before the upgrade as I need my router to just work.

Maybe 26.1 will be better, but I definitely won't bother with that for quite some time.

Next time before the rollback, please login via SSH, invoke "top" and type "o" "res" <ENTER>. This sorts the processes according to memory usage, largest on top. Then report the findings.

Will do, thank you!

In the past several hours, on the "old" version with IDS enabled, the memory utilization is still in the 30% range.
