@apenzijncoolenleuk1 @Mauio64 @Hexcede we have released an improvement to the Server LuauHeap capture process that should greatly reduce the time it takes.
Can you please test it again to see if it has improved?
I recommend testing an empty or fresh private test server first - the improvement is only live for 1 hour atm (since Jan 24 11:10 PST) and older servers are not able to get it.
Using a private test server will also avoid the negative effects on the players in the experience.
In case you still see a disconnect, we have another improvement coming next week, but it will really help us to know if the current improvement is on the right track or not.
