Hi

I has found that TCP conntrack timeout parameters are
very different beetween OVZ and vanilla kernels.
This has been checked on different servers with
RHEL 4, CentOS 4 x86_64, CentOS 5

Is it OK ?

2.6.18-ovz028stab047.1-smp x86_64
2.6.18-ovz028stab053.5-smp
2.6.18-53.1.6.el5.028stab053.6
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 120
net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_recv = 432000
net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_sent = 60

2.6.23.17 (Slackware 12.0)
net.netfilter.nf_conntrack_tcp_timeout_syn_sent = 120
net.netfilter.nf_conntrack_tcp_timeout_syn_recv = 60
net.netfilter.nf_conntrack_tcp_timeout_established = 432000
