IPTables stops logging after long uptime

[Chris Travers]

Hi all--

I was wondering if anyone has seen similar problems with IPTables/Netfilter.

I am running a firewall which consists of a small system (AMD K5 @133MHz w/32 MB Ram). It has 2 3c509 ethernet cards, is running FreeS/wan, and IPTables. It also has all QoS options enabled. The kernel is compiled without support for LKM so all of these are statically linked. I am running the Linux Kernel 2.4.18.

If the system has been up for a month or so and I try to reapply the firewall rules, something odd happens. Instead of getting the normal IPTables entries:
Feb 2 18:29:47 fwhost -- MARK --

Rebooting solves the problem. As the kernel is entirely statically linked, I can't remove and reinstall the IPTables module into the kernel. Note that restarting Syslog does not solve the problem, and syslog does log everything else correctly. so the problem appears to be with the kernel at this point.

Any ideas what causes this? Or should I file a bug with the Linux Kernel email list?

Best Wishes,
Chris Travers
