[Freedombox-discuss] Occasional freezes

[Joseph Nuthalapati]

We have recently made a switch from apache mod-php to the php-fpm
module. php-fpm runs a daemon in the background which can take up some RAM.

Maybe, you can also keep Coquelicot disabled for a while and see the
results.

We have a feature request to add a swap space by default to FreedomBox
images. Swap not working on btrfs filesystems is a bit disappointing.

This might be a bad idea, but you can probably use an attached USB disk
as the swap partition.
