Warning

Lavalink previously set the -Xmx flag to 4G in docker. This caused issues with some systems which had less than 4GB of RAM. We have now removed this flag and let the JVM decide the max heap allocation. The default is 1GB or 25% of total memory, whichever is lower.
On how to increase the max heap allocation, see here.
