Hello! I've noticed high size of kmalloc-512/2048 on my vps after a one, two weeks of work. Example: OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 83440 83411 99% 0.57K 5960 14 47680K kmalloc-512 21615 21604 99% 2.07K 1441 15 46112K kmalloc-2048 103776 103765 99% 0.31K 8648 12 34592K skbuff_head_cache I've done a little investigation (trial by error method) to discover which process keep data in kmalloc. It looks those kmalloc are used by modules from xtables-addons-1.39. I'm using ipset6, geoip, sysrq, tarpit. I greped sources for string "kmalloc", kmalloc is used by sysrq and geoip (in some other modules too but i don't use them). I'd like to ask is such usage of memory ok? Which module could take so much precious ram?:) (I suspect geoip). How much memory geoip can use in worse case (db with ipv4 and ipv6)? Can i freed this cache without reboot? (I tried flush rules, rmmod but without succes). Thank you for any answers! Marcin P.S. Is any other method to check which process/module/etc uses kmallocs? -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
