Kernel panics on get_counters after restarting iptables during heavy load

Solution In Progress - Updated -

Issue

After running ’service iptables restart’ to reload firewall rules, the system panicks. Regardless the rules have changed or not, the system still panicks.

The hardware was tested with ePSA Pre-boot system assessment tool and it came out clean. All HW components including RAM, CPU and NICs (but not limited to) were tested.

The issue seems to be related to iptables loading/unloading of ip_tables module on service restart. This might point to yet unknown bug or race condition.
