Just tried to flush those entries by unloading the kernel modules. So I issued a 'rmmod ip_vs_wlc ip_vs_wrr ip_vs'. It unloaded the first two modules just fine, but now the machine is hanging on unloading the "ip_vs" module. Either this is not supported or there's something wrong with our installation. The rmmod process is using 99.9% (on a HT enabled system, so the totals in 'top' sho 50% idle and 50% system interrupts). Is there a better way of flushing the IPVS table?
