Tick speed at absurdly high rates

I’ve had a recurring issue on my server resulting in an absurdly low tick speed causing crashes.

I’ve no idea why this is happening, was wondering if anyone can help. (Sorry if this is in the wrong place)

Im running spongeforge with a custom modpack.
Thanks for any help.

What are the mods within your mod pack? Also if you could, could you generate a timing report before it crashes?
