Sorry if this is not the correct subforum to put this in. I did use the search function of both this forum and Google in general. I submitted a ticket with the helpdesk but got sent to the forums, so I'll just copy/paste the ticket contents.
-bash-3.2# uname -a

-bash-3.2# iptables --version
iptables v1.3.5
CSF 7.52
OS: CentOS 5.4
After CSF did an auto-update earlier today, I keep getting errors trying to start it. When restarting using DirectAdmin I get:
iptables: Unknown error 4294967295
INVDROP all opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 ctstate INVALID
Error: Error processing command for line [1301] (6 times): [iptables: Unknown error 4294967295], at line 1301
When trying lfd -e from the commandline I get:
Error: You have an unresolved error when starting csf. You need to restart csf successfully before starting lfd (see /etc/csf/csf.error)
/etc/csf/csf.error contains:
Error: Error processing command for line [1301] (6 times): [iptables: Unknown error 4294967295], at line 1301 in /usr/sbin/csf
If any more information is required, I'll be happy to provide it.
