Hello all,
I have a huge memory usage when I use visual D (in VS 2200) and 
this of course is slowing down everything.
DMD Semantic Server uses up to 25-29 GB of RAM and even if Visual 
Studio is closed, two DMD processes are still running in the 
background.

How is it possible?

I am using the latest Visual D version and I didn't notice that 
the parameter to restart DMD server if it is using more than X MB 
of memory. The default setting is 0 (so never) and I think this 
is the main reason for this behaviour.

But anyway, is it possible to use almost 30GB of memory?

thanks,
Fausto

Just the other day I noticed that the updated dmd compiler version that 
powers dmdserver introduced some global arrays to keep documentation out 
of the syntax tree. These reference the source file content, so they 
never get garbage collected and can cause rather fast increase of memory 
usage.

I have a fix for that. There are a few other issues I want to resolve, 
but I hope to have a new release this weekend.

Unfortunately, this option is unlikely to help, as it doesn't kill the 
process, but frees all modules kept in memory. This won't affect the 
global arrays mentioned above.
