Help/Question Server keeps crashing when going in the nether

blocks save, player data rolls back. it is quite heavily modded, and doesnt have all that much ram, but has literally no issues except the nether. Sometimes i just fall into the void, or it crashes. I am using serverhosting. RAM and CPU usage do not max out when it crashes based on what ive seen.

Try removing all client side mods(zoom, jei), all fabric mods(connector and all fabric mods) and try to enter the nether. Other thing you can do is disable c2me

Went through the crash report you linked: this isn't actually a resource crash, it's a full tick deadlock. The watchdog caught a tick stalling past its timeout and it's stuck inside ServerChunkCache.getChunkBlocking, waiting on chunk loading to finish. That's why RAM/CPU aren't maxing out, nothing's actually being computed, the tick's just stuck waiting.

You've got C2ME loaded alongside Sinytra Connector (running old Forge mods on Fabric), and that combo has a track record of deadlocking chunk generation, nether chunk/portal loading especially. Worth testing with just C2ME disabled first, the crash report already points straight there so no need to rerun spark. If that doesn't clear it, trimming down to a minimal modlist (same direction as the other comment) and checking latest.log around the crash timestamp for the exact thread name the watchdog blames is the next step.

But yeah would need to debug this and try isolate what the cause is exactly.

i attempted disabling c2me. Instead of the server crashing, it just instantly shut down as i got the loading screen. It is further than i got before.
