Does "ifconfig" or "dmesg" show any errors? If the answer to those is no, I'd start running sar to see if there is abnormal behavior which could indicate a hardware problem. Of course, another possibility is a DDOS. Do you have any kind security monitoring or protection in place? -geoff ----------------------------------------- Geoff Galitz Blankenheim, Germany http://www.galitz.org On Tue 03/11/09 04:38 , "Timothy" timmysql at progressivemarketingnetwork.com sent: I am at a lost with this server of mine. I have replaced everything except just replacing the entire server. The server is running at a low load but every so often it starts to have high packet loss / latency(the average ms for me is 80 but it jumps to 4000 during this period) and eventually becomes unresponsive. All traffic seems normal, no unusual activity. But once or twice a month it starts to get packet loss and after an hour or two it crashes. The network itself is fine. All other servers on the same subnet work fine. Any ideas what could be causing this kind of behavior?
