I switched to Scientific Linux on both my nodes (servers). Unfortunately it didn't solve the problem. Same issue, cpu soft_lockups occur randomly, every few days. I'm wondering if its a driver issue. I saw it happen last night but caught it too late. I was connected to node remotely via ssh and left top running. I saw last top output with node load at 1400+ and 2 processes running at 100%. The node was unresponsive by the time I got to see it, but I did see one last top screen update, the last one. So I know that this problem I'm having takes at least few minutes to build up the load. I am hoping I can simply kill the 100% processes and avoid node from locking up. I've written a small program to monitor load and send me an SMS when the load spikes over 15, that way the next time I will see if I can stop node lock up by just killing the process or see if I can issue reboot command before load gets too high.
