Hope you can help me!

There is insufficient memory for the Java Runtime Environment to continue.

Your docker host needs more memory.

[tommaso-ascani]

The host is a RaspberryPi 4 - 8 GB, the only solution is not hosting the server?

[itzg]

I was thinking you might be using the default 32-bit Raspbian build, but the meminfo seems to clarify it's 64-bit. In that case, it seems like ATM7 start script is not honoring the memory setting since you requested a min of 1 GB and max of 4 GB yet the error talks about 8 GB allocation. There's only 7620 MB available, so 8 GB is too much.

[tommaso-ascani]

So i can try with another modpack or nothing to do?

[itzg]

Another modpack is definitely worth a try. Otherwise, manually editing the modpack's start script in ./data/FeedTheBeast might work.
