I have a set of computers that seem to have memory leak under 2.6 kernels
(2.6.9 and 2.6.10)
The set of machines that suffer this memory leak are the ones using ICH5 SATA
and Broadcom gigabit (tigon3) on PCI Express, as opposed to other machines with
IDE and Intel gigabit. Both sets of machines use hyper threading.
On all machines, the memory report below is after restarting all but init
processes, so memory consumed by applications is less than 50 MB.
/proc/meminfo just after booting:
