I am having a problem with my new server, P4 3GHz CentOS 3.3 with Plesk 7.5.3.
The problem is it hangs, I can ping but I cannot access using any of the standard methods such as ssh, ftp and http. Only thing I can do to get rid of the problem is reboot the machine.
I saw once the iowait was hitting 100% on the top display. Obviously the server hangs because no CPU resourses due to the iowait situation. But I don't know how it happens even though I am not doing anything and the server virtually doing nothing except DNS service.
Has there anyone experienced the similar problem?
I have been using AMD XP 200 RadHat 9 with Plesk for years but seen nothing like this.
