What is using the "size-32" ? And it this normal to see that on a laptop with 4G RAM which is only running X, KDE, Compiz+emerald, +/-10 xterms and a firefox which is closed as soon as it is no more used. Before you ask : [root@tux proc]# zgrep SLAB /proc/config.gz CONFIG_SLAB=y CONFIG_SLABINFO=y # CONFIG_DEBUG_SLAB is not set [root@tux proc]# uptime 11:34:50 up 6 days, 20:30, 13 users, load average: 1.42, 1.35, 1.23 so that may limit the actions or informations I can collect, but any details you want, please feel free to ask.
