This smells either like a slab backed memory leak or something went crazy and allocate huge amount of slab. You have 3.6G (or of 4G available) of slab_unreclaimable. I would check /proc/slabinfo for which cache consumes that huge amount of memory. -- Michal Hocko SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
