Description of problem: There are "page allocation failure"s and the box is generally unstable. Server info: Intel P4 2.8GHz, 2 gigs RAM 3Ware 9000 RAID card (12x200 gigs in RAID 50, for 1.7TB) NFS server only XFS filesystem for RAID partition Fedora Core 2 Gigabit ethernet (e1000) Version-Release number of selected component (if applicable): Kernel 2.6.9-1.6_FC2. How reproducible: I have crashed the box by doing a ~3 gig mysqldump via NFS while simultaneously downloading via ftp a 4 gig ISO. This is via gigabit ethernet. The debian boxes that NFS mount it also generate lots of: nfs: server 10.1.1.1 not responding, still trying nfs: server 10.1.1.1 OK Steps to Reproduce: 1. Throw loads of data at the box, particularily via NFS to the XFS RAID partition. 2. Just wait awhile... Actual results: Box OOPs, has "page allocation failures", just croaks outright, becomes sluggish, etc. Expected results: Be really fast & stable. Additional info: See attachment

XFS is trying to do a really huge allocation. Little surprise that it falls over under load I guess. XFS isn't a 'supported' filesystem of Fedora, so your best bet is to tell the SGI folks who maintain it about this problem, and whatever they fix we'll pick up the next time we rebase.

Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
