Severity: 3-Major


In a VIP-on-VIP (looped) situation, HTTP on one virtual server uses/reuses an existing 'http_proxy_opaque' whilst still in use by another virtual server that causes unexpected state changes in the opaque which may cause tmm to core.


Traffic disrupted while tmm restarts.


-- Explicit Forward Proxy SSL Orchestrator, in other words an L3 Explicit Proxy which is usually deployed in a VIP on VIP configuration -- Hostname resolution using explicit 'RESOLV::lookup' iRule in HTTP_PROXY_REQUEST on the explicit/client-facing VIP
