Hi,
How can I debug what's causing this ever increasing number of
clash_resolve counters on my router?
user@host# sudo conntrack -S
cpu=0 found=11145 invalid=48749 insert=0 insert_failed=1691
drop=1691 early_drop=0 error=1792 search_restart=0 clash_resolve=901502
chaintoolong=0
cpu=1 found=10492 invalid=48616 insert=0 insert_failed=1748
drop=1748 early_drop=0 error=1422 search_restart=0 clash_resolve=907423
chaintoolong=0
This is on a router with a pretty basic NAT setup - NAT anything on the
LAN (192.168.0.0/16) to a single WAN IP address. Two Interfaces, eth0
(WAN) and eth1 (LAN)
The same output a minute later:
tim@ferrari# sudo conntrack -S
cpu=0 found=11150 invalid=48766 insert=0 insert_failed=1691
drop=1691 early_drop=0 error=1792 search_restart=0 clash_resolve=901897
chaintoolong=0
cpu=1 found=10497 invalid=48631 insert=0 insert_failed=1748
drop=1748 early_drop=0 error=1422 search_restart=0 clash_resolve=907859
chaintoolong=0
So ~300 clash_resolve's a minute.
Kernel 6.6.30
Is there some way I can debug what's triggering the clashes?
Many Thanks,
Tim
