Bandmin cron error

[Jeet]

For the past couple of days, I've been receiving the following email from Cron
<root@serv​er> /usr/local​/bandmin/b​andmin

iptables: Unknown error 18446744073709551615

Strange thing is that I have two dedicated servers running centOS/cPanel/WHM and I'm getting the exact same errors for both the servers. So I wonder whether this has happened due to any recent upgrade of cpanel?

Any way to fix this?

Thanks,

Hello

To clarify, the two servers are not VPS machines? If not, I have seen cases in the past where CSF firewall rules interfered with Bandmin. Is CSF enabled on these servers? If so, I suggest temporarily disabling CSF, and checking to see if the issue persists. If it does not persist, then that confirms CSF (the iptables rules it uses) is the root cause of this problem.

Thank you.
