Dont know what to make of this, I pretty much get it every other time I call rdmd. It'll alternate between running fine and then giving me this error...

C:\Program Files (x86)\Notepad++>rdmd J:\Code\statproc.d
std.process.ProcessException@std\process.d(550): Failed to spawn new process (The process cannot access the file because
 it is being used by another process.)
----------------
0x00434C59

0x00403C9C
0x00403D17

0x76B533CA in BaseThreadInitThunk
0x775A9ED2 in RtlInitializeExceptionChain
0x775A9EA5 in RtlInitializeExceptionChain

Any ideas?

Well, Windows has file locks, so tyically, if one program has a file open, another can't have it open. So, I'd guess that either something has the file open when you're running rdmd, so rdmd can't access it, or rdmd is trying to access it from multiple processes and sometimes one of its processes is accessing it when another one tries to. But I don't know if rdmd creates multiple processes or not.

Personally, I wish that Windows didn't have file locks... :(

It's locked unless it's specified during the call to `CreateFile()` that the file can be shared for reading/writing (FILE_SHARE_READ / FILE_SHARE_WRITE).

rdmd creates an executable and runs it immediately. If you have an antivirus, it may not complete its job in this rather short timeframe. Just run it again, AFAIK, rdmd caches the executable from the last compilation.

My guess, it's the executable file, which is opened by another process, if it's not completely written, running it would give even more funny results :)

And the executable file being run must not be shared for writing, because it's mapped.

Decided to do a fresh install of windows, and problem has one away. It seems no matter how careful you are to keep your system lean and clean windows eventually starts grinding gears.

Thanks,
