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.

Oh Sh....
Swap files are not allowed on btrfs
manpages say:
<blockquote type="cite">
*swapon* may not work correctly when using a swap file with some
versions of *btrfs*. This is due to btrfs being a copy-on-write
filesystem: the file location may not be static and corruption can
result. Btrfs actively disallows the use of swap files on its
filesystems by refusing to map the file.

So I have to generate a swap partition on a micro-SD card. I think to
have read this was discouraged because wear leveling was then inefficient.
I would put a remark in our hardware section to avoid devices with <1 GB
RAM.
I will do this after I am sure my issues come from running out of RAM.

Thanks for the hint, but it runs into bug #913481.
I will do it according to the debian wiki > swap
Nevertheless, it would be better to find the cause of the freezes by
investigating some log files.
Currently I just see the authentication errors in coqueliqot and
actually also in mediawiki - but both work.

I am considering to set up a SWAP-file on FBx in order to avoid the

I doubt it, but can not say for sure. Are you aware of the
dphys-swapfile package? I suspect just installing it might do what you
want.
