server stopped with error

[GeneralDisarray]

That's a generic access violation exception, ie attempted to read/write an invalid memory address - the number in [] - both of those are clearly not in process memory space (well, "clearly" to a Windows developer).

The error message itself is AC's own though, so the exception has been caught internally.

flowtron, consider extending fatal() function to have the caller info (eg __FILE__ and __LINE__) to help trace the source of these errors in general.
