Subject: ipset memory usage
Date: Sun, 25 Sep 2005 08:31:09 +0200	[thread overview]
Message-ID: <4336442D.3090404@free.fr> (raw)

Hello,

The ipset modules seems to eat a lot of memory :
with a test set of  :
- 150 000 networks in a nethash
- 10 000 hosts in a iphash
ipset sometimes fails with out of memory errors :
"kernel: allocation failed: out of vmalloc space - use vmalloc=<size> to 
increase size"

The VmAllocUsed variable from /proc/meminfo goes from 6Mo to 160Mo after 
loading sets.

Is this normal ? Is there some way to reduce memory usage ?

Thanks
