Hi Have you seen Slab corruption before ? I got it when deleting a service when there is real-servers left It's not related to IPv6 or fwmarks any "-D" causes it if there is rs attached for that service (and it's not bad RAM).
Do you have this patch which is already in nf-next: http://archive.linuxvirtualserver.org/html/lvs-devel/2010-09/threads.html#00039 static inline void ip_vs_service_put(struct ip_vs_service *svc) { atomic_dec(&svc->usecnt); } There is one atomic_dec after free but I'm not sure if it matches the dump below. If in doubt just add svc = NULL in ip_vs_genl_set_cmd after the call to ip_vs_del_service.
ex. # ipvsadm -D -f 21 -6 Slab corruption: size-512 start=ffff880001760488, len=512 Redzone: 0x9f911029d74e35b/0x9f911029d74e35b.
