[Dxspider-support] Weird node issue that prevents user logins

[Dale Harwood]

Several years back I had a Centos machine that would run for weeks and 
for no reason would stop talking to the network. It ended up being bad 
caps on the motherboard. Replaced them and still works to this day.
Does other network activity still run as normal?
