[pve-devel] nf_conntrack: table full, dropping packet error

[Alexandre DERUMIER]

Hi, 
This morning I see a lot of nf_conntrack error in /var/log/messages. 


Is it related to redhat kernel ? 
How can I disabled it ? 





kvm2:~# iptables -L 
Chain INPUT (policy ACCEPT) 
target prot opt source destination 


Chain FORWARD (policy ACCEPT) 
target prot opt source destination 


Chain OUTPUT (policy ACCEPT) 
target prot opt source destination 
kvm2:~# cat /var/log/messages
