From: Vasu Dev <vasu.dev@xxxxxxxxx> The FC-GS-3 sepc requires to wait for least 3 times R_A_TOV per sec 4.6.1 "If the Requesting_CT does not receive a Response CT_IU from the Responding_CT within three times R_A_TOV, it shall consider this to be a protocol error." This means added four new states with management server could add significant delay with multiple retries on default 12 second timeout(3 * R_A_TOV), so instead just skip these states on very first timeout on any of these states to not stuck with states for such longer period.
