I've had my server setup for almost a week now and things have been pretty wonderful; running on a quadcore with 2 GB of ram. That said, this morning I woke up and it was.. down? Well, not exactly. It's primarily a web server. I tried to access its pages and it didn't timeout, but it was impossible to connect. Sometimes I was able to get little bits of the webpages. SSH was unable to connect. Eventually, it got back up to normal speed. How to I determine what it was doing during this time? I checked the apache error log, but there was nothing relevant there. When I did connect, I ran tops and found that 'yum-updatesd' had 6% of the MEM and large values in the other columns. I stopped this service and removed updatesd. Did I solve the issue?
