When executing ipset -L <ipset_name> to list the contents of a
(medium-size) ipset I am getting the following kernel error (from
/var/log/messages):

Any idea what may be the cause? The system is Pentium2-based with 288MB
RAM and kernel 2.6.34.7-56 with xtables 1.30 and ipset 4.4 installed.

According to the logs below, it's a bug in deleting an entry from
an iptreemap type. I'll look into it at the weekend, thanks for reporting!

It might be related to something I did (and was very impressed with as
far as ipset goes): I had defined a /16 range of addresses in that
ipset, but later on had to delete a single address from that range with
the ipset -D command.
When I executed ipset -L (and got the kernel error) I found out that
ipset had readjusted, 'automatically', the IP range, which I found quite
good.
For example, let say the original IP range was 10.10.0.0-10.10.255.255.
Then I deleted 10.10.100.100 and issued ipset -L. The previous range of
10.10.0.0-10.10.255.255 is now split in two, 'automatically' by ipset,
to 10.10.0.0-10.10.100.99 and 10.10.100.101-10.10.255.255 - quite
impressive, though unfortunate that I get the kernel error, which I
suspect was caused by the deletion I did previously.
