Hello to all, I recently installed a HP Proliant server with Ubuntu 12.04.1 LTS and followed the perfect server install tutorial. The server has 2 CPU of 3,06 GHz and 2 cores each one and 4 GB RAM Now, the problem is: After 7-8 hours my load jumps ower 100, i cannot execute to many commands (just ps aux, ls -a, kill) and in ps aux i see a lot of CRON processes wich i cannot kill. I execute the kill -9 pid command and nothing happens. I cannot use reboot. I have to shut down the server from the power button. Have anyone had this problem? Is there a bug or something? Now i have removed ALL from cron jobs and wait to see if the problem appears again. So, as i sayd before, if someone had this problem or knows anything about it please reply and tell me how can it be fixed. Thank you all in advance. Best regards
I start to belive that this is a kernel problem. I saw on the server that, when a process hungs up i get a message wich tells me that the process is hunged up and ttells me to do: echo 0 > /proc/sys/kernel/hung_task_timeout_secs to disable this. I am thinking to downgrade the kernel. Any solutions from anyone?
