Im running CentOS on a WordPress/Apache server that was working properly up until a week ago, no changes. All of the sudden networking starts failing last week and since then ive been unable to get it back up and stable. When networking wen down, rsyslog stopped working as well so I have no logs to go through at this time. Rsyslog was set to log to a network store and also go to Logstash, but since the networking is down nothing is working.  The only way that I was able to get networking back up and running was to add a new interface through VMWare, configure eth2 and set to DHCP, and then restart networking... it will then work for a few minutes and then stop again.I've disabled iptables, syslog, fail2ban, etc but I can't see what is stopping newtworking from working normally. Packet sniffing its IP on the networking firewall doesn't show any packets trying to leave that system. Restarting networking shows the interfaces come up and down normally and everything looks good in ifconfig. Just no packets will leave that system or come to them.  I have 3 networks on there, one to NFS (eth1), one normal eth0 and then an eth0:1 device that are on the normal subnet. Running out of ideas so was hoping maybe ya'll had some clues I could start on. Or, if my idea on logging failing could cause these other issues. I've seen apache fail if logging was not working, etc. 
Could failed logging break networking? Logs are down, network is down?
