iptables-restore: line 42189 failed

[ainsley99]

I have tried set the script on about a dozen machines, most work, but on a few I get this error ... COMMIT ===== /sbin/iptables-restore ===== iptables-restore: line 42189 failed

Rules update failed: exit code 1 at line 0

This error seems a bit vague, is it known? The line number varies between machines.
