Unexpectedly shrunk window

Question

I run a major media upload/download site and I noticed these:

Is this serious or background noise due to the big file sizes and is there any tweaks I can add to /etc/sysctl.conf to improve and prevent issues?

Solution

Welcome to the Internet. It's perfectly normal for other machines to break the rules when they're talking to you. You can't fix the world, nor do you need to.
