Over the last month or so my CentOS server has been crashing for reasons I do not know. It has been running for over a year with regular yum updates without problems. The load on the server is perfectly normal with CPU usage at 5-6% and RAM usage at less than half of 32GB of RAM (multiple smaller game servers run off of this box). I am unsure if this is a software issue at all.
I have pasted my /var/log/messages file around the time of my latest crash all the way up to the crash. Because I am a CentOS newb, this is gibberish to me, so I am curious if anything in the file points to a crash of some kind? Or if there are other logs I could check and paste? If not, it would lead me to believe there is a hardware issue or overheating.
watchdog is doing what it is supposed to do - it is a daemon that resets the system when something, usually software, gets to some defined - not at all acceptable - point.
In this instance it won't allow what is going on with your ethernet (network) port. .. your NIC card.
This is generally hardware - loose connection, bad component, and so on. If this happens every time within a short period of booting, then this may be caused by setting network configuration incorrectly.
I don't know enough about this to give you more information - maybe someone else does.
You do need to make sure about the error relating to: Can't open file '/var/spool/abrt/oops-2....' get resolved - check disk full, check directory /var/spool/abrt exists and is writable

It is the NIC card and the TCP protocol stack that are bothering watchdog. I know enough red hat to know I do not know how to diagnose and then remedy the problem.
Start with connectivity: ports, ethernet cables, maybe the NIC card.
If that does not help then assume you misconfigured TCP - start with man ifconfig. I assume since everyone uses that, Red Hat does, too.
Need to use dd to generate a large file from a sample file of random data. This is because I don't have /dev/urandom.
I create a named pipe then:
dd if=mynamed.fifo do=myfile.fifo bs=1024 count=1024
but when I cat a file to the fifo that's 1024 random bytes:
