Subject: ip_conntrack_core - possible memory leak in 2.4

hi,

i have there MontaVista based router, with 2.4.17_mvl21-malta-mips_fp_le
kernel. I think, there is memory leak in ip_conntrack code. There are
eta 500 conntrack connection all the time. But after some day i get
"ip_conntrack: table full" in kmsg.
/proc/sys/net/ipv4/netfilter/ip_conntrack_max have 3072 value.
grep ip_conntrack /proc/slabinfo
ip_conntrack        3006   3250    384  319  325    1
^^ there are 3006 allocated conntracks
cat /proc/net/ip_conntrack | wc -l
30
^^ in table are only 30 lines.

Acording to this:
http://lists.netfilter.org/pipermail/netfilter-devel/2004-May/015628.html
i don't think, this is fixed in 2.4 tree, but i can't test it with newer
version.

Thanks
