I have an FC3 server that's been running fine for months. I made some changes to it's role recently (it now does full backups of our Windows PCs), and if I leave a backup running long enough I can peg the physical memory at 1 Gig of RAM usage within 24 hours. I have had several hard lock ups in the last few days.
Here's a summary of the changes:
Updated to 220.127.116.11 kernel
Installed a Promise SATA Non-RAID controller
Installed 4 drives on SATA controller in a software RAID-5
I've been running rsync against smbmounted drives for hours at a time.
Does anyone know if either libata or sata_promise has any documented memory leaks that would cause this problem? I suspect rsync and smbmount too since I've been syncing around 50 gigs of data per run. MD is the last thing on my list because I think it's been the most tested out of all of the new elements on my machine.
Can anyone point me to a memory profiler that allows me to view my current RAM in a useful way? I've checked out valgrind and others, but they're all application specific. I may try using it on my next rsync just to see if I can figure anything out.
