hi thanx for responding. some info to you all... the linux box with 2.4.19 kernel & iptables 1.2.7a has 768mb ram its ip_conntrack_max shows 48632. moreover the ip(=>> ipA) in the message file is a valid ip and not a private one & its going to a valid ip in internet. the very interesting & confusing part for me(& hope for others?? ) is why a day ago with iptables 1.2.6a there was no error message ???.. as i mentioned in last mail the only difference is that i have as module--> ip_nat_h323.o & also ipt_helper.o one last info to add here---why only this message for >>ipA<< when the box is handling more than 500 valid ip & above 200 private ip( of 10 series),..slabinfo shows... ip_conntrack 5150 6660 320 490 555 1 pls i need help to know where things went wrong for me.. if someone else have experienced the same can they give their experience/suggestions ?? thanx in anticipation...
