hi, have u enable sar on the server? by sar u can get the historical data of the cpu and memory load at the time of hanging. also u can get a kernel dump at the time of hang up to check for actual cause. we too had a similar prob and the cause was external hba drivers other than the bundled ones.

Hi, I have two incidents when server (primarliy MySql) hung and it had to be hard booted. Under such circumstances, how do I find the cause of the failure. I have collectd service running on the server and it provides graph of parameters such as memory, load etc... from the graph I dont see any heavy usage, except load was a bit high but not so much that a 'linux' server should behave like windows. I want to know where to look for information on such an incident. Also, where does kernel log cause of reboot ? does it happen at all ? I believe it doesn't. yet, if I am missing something, then let me know. Thank you. DoOrsOfpErcEpTiON [Non-text portions of this message have been removed]
