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?
