[ipset] Minor sleep bugs

[ipset] Minor sleep bugs

[Ismaël BALLO]

Hi,

I use:
ipset v2.2.9a
iptables 1.3.6
on kernel 2.6.19.7 (from kernel.org) on FC6.
All has been compiled as said (http://ipset.netfilter.org/install.html )

This behaviour seems to happen where there are lots of bindings.

I've got some questions :


1/ How to find optimal parameters for  hashsize,probes , and resize ?
(where we've got lot of bindings ..)


I've got such errors in my /var/log/messages (but applying the command is ok !)
