Jon,
I did some more research into the memory leak you mentioned...
In your original email a while back, you said you were on NT at that time, but I gather the machine's been upgraded to 2000 Server, based on
this post. You also mentioned in that post that you were checking memory and resource usage with the Task Manager.
I tried doing the same thing on my XP Pro machine today, and found the "USER objects" and "GDI objects" columns in Task Manager (never knew they were there before). I think this is what you were probably using as well, but you mentioned in your other post that the resource usage was in percentages, and it doesn't look that way to me (maybe just different in XP). Anyway, I did find a resource leak that causes the GDI objects to go up by 4 every time you click on one of the column headers in the player list or flight plan list. If you keep clicking the headers, it just keeps leaking more and more.
However, I didn't find any other leaks, and I'm thinking it's maybe not the same thing you were seeing (unless you just like clicking column headers a lot while the server is running).
So.. First, can you confirm what I've said here, to make sure we're on the same page. Then could you please try doing a few things in FSHost (running it, connecting, disconnecting, options window, clicking column headers, etc.) and see if you can find something in particular that consistently leaks resources? I'm thinking that maybe something is different in 2000 Server.
Thanks!
Russell
