Faulty RAM causes file write errors that lead to main.ttw corruption. Run Windows Memory Diagnostic or memtest86.
To understand the fix, you must understand the lock.
In 7 Days to Die, the "exclusive" refers to exclusive write access to critical world files—specifically the region files (.7rg), the player data (.ttp), and the main.ttw index. When the server starts:
If the server cannot obtain an exclusive lock on any required file, it hangs indefinitely on "Initializing exclusive". It will not time out. It will not skip the file. It simply waits forever.
This is a file access deadlock, not a network or performance issue.
Linux:
ps aux | grep 7DaysToDieServer
sudo pkill -9 7DaysToDieServer
sudo lsof | grep "YourSaveFolder" # Find any process touching the save
Windows (Task Manager or command line):
taskkill /F /IM 7DaysToDieServer.exe
Also check for 7DaysToDieServer_Data in background processes.
If the error persists, your region files may be corrupt.
What happens? The server regenerates all chunks that were deleted. You will lose any player-built structures in those chunks, but your server will start.
Alternative: Use a 7DTD region editor (like 7D2D Region Tool) to scan for corruption. Look for files with 0 KB size – delete those specifically.
