They folded out of the system immediately
after I received the message, without so
much as a "Thanks for saving us from
becoming plasma on Tau Ceti, Durandal".
The Halos kill all life with enough biomass and/or sentience. We dont know how the Halos do it but they did. With no new hosts the Combat forms break down, becoming Carriers. The carriers would break down, releasing the Infection forms. After that I dont know. We dont even know if dormancy is a natural trait of the Flood. We know that they were contained for study on the Halos/Gas Facilities after the Halos fired, so the Flood may have been kept dormant by the Forerunners/Sentinels, not naturally.
Also: Sentinels were created before the Forerunners discovered the Flood. They maintained the Gas Facilities, like the one we fight on as the Arbiter.
