What this error means, and every way to fix it →

critical

The server ran out of memory

The server used more memory than the heap it was given and stopped. Give it more RAM (raise the -Xmx or RAM setting) so there is headroom above what the pack needs, and lower view-distance in server.properties if the machine has no more to give.

which explains: The server stopped responding for 62 seconds
The stall is a symptom of the finding above, not a separate problem.

which explains: The server crashed and then hung
The hang is the aftermath; the crash above is the story.

which explains: The tick loop fell 4732ms behind, 94 ticks in one go
The tick loop falls behind because of the finding above, not on its own.

Two mods clash inside this pack

A mod patched the game expecting a library or another mod that is missing or the wrong version, so the game crashed when that code ran. The stack trace names the mod (look for handler$...$modname, or the .mixins.json config). Remove or exclude that mod server-side, update it to a build for this exact version, or ask the pack author to ship its missing dependency. The trace points at bettermobcombat.
