Subject: ZONE_NORMAL exhaustion (dcache slab)
Date: Mon, 21 Oct 2002 13:40:37 -0700 [thread overview]
Message-ID: <302190000.1035232837@flay> (raw)
My big NUMA box went OOM over the weekend and started killing things
for no good reason (2.5.43-mm2). Probably running some background
updatedb for locate thing, not doing any real work.

Big things out of slabinfo:
ext2_inode_cache 554556 554598 416 61622 61622 1 : 120 60
dentry_cache 2791320 2791320 160 116305 116305 1 : 248 124
By my reckoning, that's over 450Mb of dentry cache that's refusing to shrink
under pressure. ext2_inode_cache ain't exactly anorexic either. Hmmm .....
Any good ways to debug this?
