I have launched the container using these parameters :

docker run --name tileserver-gl -d --init --restart=unless-stopped -m 14g --memory-swap=22g --memory-reservation=10g --cpus=6 --ulimit nofile=65536:65536 --pids-limit=150 -e NODE_ENV=production -e NODE_OPTIONS="--max-old-space-size=11264" -e LIBGL_ALWAYS_SOFTWARE=1 -e UV_THREADPOOL_SIZE=6 -v /var/data:/data -p 8080:8080 maptiler/tileserver-gl:v5.5.0-pre.7 --fetch-timeout 20000

For the record :

free -h
total used free shared buff/cache available
Mem: 29Gi 13Gi 15Gi 227Mi 624Mi 15Gi
Swap: 8.0Gi 3.1Gi 4.9Gi

I have these (new) errors in the docker logs :
