I'm not really sure what happened here, but kernel logfile and serial console log said this: __alloc_pages: 0-order allocation failed. __alloc_pages: 0-order allocation failed. __alloc_pages: 0-order allocation failed. __alloc_pages: 0-order allocation failed. eth0: memory shortage __alloc_pages: 0-order allocation failed. __alloc_pages: 0-order allocation failed. __alloc_pages: 0-order allocation failed. ... System was unstable and hard-locked when I did a sysrq-p. syslog died when the error showed up, so no data is available. There's 1GB in this system with Apache (128 children) and MySQL (192MB keycache) running. I'm not sure how to recreate the error. System was running fine for 5 days before it showed up. -Vibol - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
