Hi, Guys My Linux system (2.6.18, x86_64, RHEL5) only has 1G memory, and I would like to use blktrace (1.0.1) to capture 20 minutes of IO traces with medium IO traffics. After 20 minutes, system would hang. I think at this phase, blktrace is exiting and printing the summary section that number of events captured on each cpu. I'm guessing the system hang due to out of memory. (I can ping the system, but can't login). I'm wondering is there a workaround?
