Our old default poll interval was 30 seconds so this doesn't change anything. I know DeadRat takes more than 30 seconds from "shutdown -h now" to power off. All modern CPUs have a thermal shutdown builtin. Think of _CRT as more of "system temp too high, shut down as soon as you can." -Nate ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
