wonderHey I get this error almost everyday (once-twice per day) when my TF2 crashes.

I use low masterconfig. I disabled steam overlay and it didn't help.
Actually, I got this error in my tf2 server testing today. This was on cp_sunshine, looking at a wall. I'm fairly certain its due to tf2's memory allocation not having enough memory to store the texture data to.
I was running the server with 1gig ram, and it performed nicely on cp_process. Switched to sunshine and a minute later it crashed.
