1.4.1 has fewer bugs ;) but not related to this. 1036 close enough... might be a bug there (should be 1023 or 1024 exactly) in the way 1.4.0's reserving pages. but, that does mean all your memory's allocated. 'stats items' will show you which slab classes are having evictions. Then you can adjust your growth factor to better cover it. Also, match 'stats slabs' up with 'stats items' to see if the evictions in a particular class map to a slab with most of your pages. If there aren't enough pages assigned to a heavily used class, that usually means the access pattern changed over time and you need to restart memcached to have it re-dish them out. -Dormando
