Your server freezes, watchdog shuts it down then, that's not a bug.

Unless you can pinpoint a cause of lag (the freeze), this is not an accepted bug report.

The thing is: the server does not do much (no players online in MC). So I wonder how the server can be laggy.

Spawn chunks are always loaded, even if nobody is in the world; you could also simply be assigning too little memory for it to keep up, or have a data pack that has an infinitely looping function.

Spawn chunks are kept simple by purpose and the datapack does not use functions.

With the reduction of the default size of spawn chunks in 24w03a, can you still confirm this issue?

I haven't upgraded to 24w03a or later yet but the problem hasn't occured for several weeks now. Maybe it's fixed now somehow.
