Server Freeze Up Under Load
Posted by eli2009, 05-08-2012, 10:14 PM I'm having a problem with my centOS server. During high load the system became non-responsive, I couldn't connect via ssh or http, but it responded to ping. It's Quad Core E3-1220 with 8GB RAM. Please help me. Here is dmesg output:
Posted by storminternet, 05-09-2012, 04:59 AM Hi, Can you post here the result of top command when load reaches to high ?
Posted by eli2009, 05-09-2012, 05:49 AM the load was around 50
Posted by gigatux, 05-10-2012, 09:47 AM 50 is obviously a very high load. It's quite possibly the load was high due to massive disk I/O. What exactly were you expecting to happen under a high load situation? If your disk is thrashing, even things like SSH will start to respond very slowly. You will always get a response to ping as this does not rely on any disk access (and it's all in the in-memory kernel).
