This bug can also be seen if you are seeing errors like these:

Mar 6 17:27:29 server kernel: [14438.135859] compcache: Error allocating memory for compressed page: 60594, size=4096

You can also see it when you print swap information with the command swapon -s – if compcache is enabled, one of the swap entries will be “ramzswap”.

To disable compcache completely, do this:

 rm -f /usr/share/initramfs-tools/conf.d/compcache && update-initramfs -u

The file compcache contains this line – which is what enables (and sizes) compcache:

 COMPCACHE_SIZE="25%"

create file /etc/NetworkManager/dnsmasq.d/dnsmasq.conf

with this content:

all-servers
cache-size=10000
addn-hosts=/etc/hosts
neg-ttl=3600
local-ttl=3600
bogus-priv

for /etc/hosts use Hosts adblocker
