Subject: [xtables-addons] memory usage in module geoip (probably)
Date: Fri, 20 Jan 2012 17:12:58 +0100 [thread overview]
Message-ID: <4F19928A.7050005@mejor.pl> (raw)
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?
