It starts to become a non-responsive from time to time with 100% cpu usage eventhough there is no applications running except a browser. I have been running centos 4 for the past 6 months without any problem with regular update. Now, I have to reboot whenever it shows signs of a non-response. It starts to exhibit this behaviour a cople of days ago. I could not figure it out the reason and need help. Is there any tools to troubleshoot this ? I have tried top, system monitor.. I have attache screen shoot of system monitor if it helps.
