Downloaded the latest source for the 2.6.24 kernel and ran the script make_debug_config and then compiled the kernel. I did change one thing and that was to pick AMD instead of generic 64 bit. It compiles and runs but has a severe memory leak because after an hour of normal operations it chews up 6 gigs of my 8 gigs of ram. And when I turn off the VZ service killing all VMs it still has 6 gigs in use.
Not sure if I'm doing something wrong. I'm trying to troubleshoot a kernel lockup related to disk IO on an EXT3 filesystem. Is this a bug? Anything that I should do to further investigate this?
Here's the original crash. I am running a 1.5 T Seagate drive. I did install the drive bios patch that's supposed to fix it but it might still be the drive. It crashes when running rsync backing up all my other servers. And I have a lot of hard links and a huge number of files in the system. Additionally the same drive and scripts crashed on another server so the problem is definitely with the drive or what I'm doing. (other hardware eliminated)
