I have 3 servers, all hosting clients gameservers (the same game on all servers) but I'm having an issue with one server and it's crashing for some reason. I am unsure of why it is crashing and I am getting a "Network error: Software caused by connection abort" problem with PuTTy when it happens. Straight after it crashes I ping the IP of the server and it says that it's online, so it's automatically coming online after with no delay whatsoever, but when I type top it says that the uptime is about 1 minute, so I'm confused.

Any suggestions, at all?
The only thing installed is the OS (CentOS) and the control panel hosting the gameservers, and java.

I have avalible 32GB's of RAM, yet only using 10GB's.

Did you check the logs (/var/log/messages, /var/log/dmesg, /var/log/syslog, etc) ?

I researched abit more and found out that it was a RAM issue apparently, I had my RAM sticks changed and looking at /var/log/messages use to have alot of BIOS errors (or looks like errors), messages rather.
