WCCP can stall during a restart.

If the WCCP router uses an identifying IP address which is not the same as the source IP address on the packet (which is allowed by the WCCP spec) then the TS client side WCCP code can fail to properly generate an assignment. This happens during a window after a restart when TS is trying to set up the WCCP view while the router has not yet realized TS has restarted. The client WCCP logic then soft stalls and doesn't generate a new assignement when the router responses are processed.
