Eventual (after many rounds) crash, and why it happens

[eezstreet]

After many rounds (depending on the computer, sometimes as high as 100, sometimes as low as 20) the game will crash.

The following factors influence it:
- Changing maps
- What kind of PC you have

It's caused by a slow (but steady) problem: the game slowly loads all of the models and sounds and never purges this data.
As a workaround you can do snd_restart in the console and it will purge all sounds. This isn't perfect however since lifts and doors will not play their looping sound anymore.

I meticulously logged all of the memory information - both zone and ram being used. I also periodically checked the zone details to get further information (zone_stats/zone_details)

before round 1: 498MB RAM (146.54MB zone)
round 1: 513.4MB RAM (156.22MB zone)
round 2: 534.8MB RAM (165.42MB zone)

I have the same problem, the game freezes up regularly after many rounds. The memory usage of my MB2 slowly increases from round to round, map to map, until it reaches the point where it crashes. It basically functions like a memory leak.
